On the morning of July 11, 1993, the Mississippi River crested at 49.58 feet at St. Louis, Missouri, nearly 20 feet above flood stage. By the time the waters finally receded in late August, the Great Midwest Flood had inundated 20 million acres across nine states, caused an estimated $15 billion in damage, and done something that rarely makes numismatic headlines: it systematically destroyed enormous quantities of circulating Federal Reserve notes stored in bank vaults, teller drawers, ATMs, and Federal Reserve branch facilities throughout the central United States.
The Scale of the Destruction
Understanding the currency impact of the 1993 flood requires understanding how physical cash moves through the Midwest banking system. Federal Reserve notes in active circulation flow from the Bureau of Engraving and Printing in Washington, D.C. and Fort Worth, Texas through the twelve Federal Reserve Banks and their branches, then out to member commercial banks, and finally into the hands of the public. In 1993, the four Federal Reserve Districts most severely affected were the Kansas City Fed (District 10, letter J), the St. Louis Fed (District 8, letter H), the Chicago Fed (District 7, letter G), and the Minneapolis Fed (District 9, letter I).
When levees failed throughout July, communities did not always have time to evacuate their financial infrastructure. In many small Iowa and Missouri river towns, branch bank vaults sat at or below ground level. Floodwaters contaminated currency with silt, agricultural chemicals, sewage, and biological material. Paper currency that was wet for more than 24 to 48 hours typically suffered irreversible structural damage: the cotton-linen substrate delaminated, ink migrated, and serial numbers became illegible. Currency that dried improperly after submersion fused together in dense, brick-like masses that the Federal Reserve technically classifies as “mutilated currency.”
The Bureau of Engraving and Printing’s Mutilated Currency Division in Washington, D.C. processed thousands of flood-damage claims after 1993. If you encounter heavily stained, structurally compromised notes from this era with H, J, G, or I Federal Reserve district letters, do not immediately assume they are worthless. Some partially legible flood-damaged notes have found homes in topical “disaster currency” collections, particularly when accompanied by provenance documentation from the original bank or owner.
The Federal Reserve’s Emergency Response Protocol
The Federal Reserve System has well-established procedures for responding to mass currency destruction events, drawing on protocols refined after hurricanes, industrial fires, and previous flood events. When the scale of the 1993 flooding became apparent in early July, the Kansas City Fed and St. Louis Fed activated emergency currency request procedures, submitting accelerated orders to the Bureau of Engraving and Printing for expedited shipments of new currency.
The primary series in production and distribution during the summer of 1993 was Series 1990, bearing the signature combination of Secretary of the Treasury Lloyd Bentsen and Treasurer of the United States Katherine Davalos Ortega. Wait, that combination requires a correction: Series 1990 notes carry the signatures of Nicholas F. Brady as Secretary of the Treasury and Catalina Vasquez Villalpando as Treasurer. When the Clinton administration took over in January 1993, new signature plates were being prepared, and Series 1993 notes would not reach full production circulation until late 1993 and into 1994. This timing is crucial for collectors: essentially all emergency replacement currency flowing into the flood zone during the summer of 1993 bore Series 1990 designations with Brady-Villalpando signatures, or in some cases older Series 1988-A notes (signatures of Nicholas F. Brady and Rosario Marin predecessor Catalina Villalpando) that had not yet been retired from circulation stocks.
The BEP’s Fort Worth facility, which had opened in 1991, played a significant logistical role in accelerating deliveries to Midwestern Federal Reserve banks because of its more central geographic location. Fort Worth-printed notes during this era can sometimes be identified by the small “FW” plate position indicator that appears on notes produced there, providing collectors with an additional variety to seek.
Star Notes and the Replacement Paper Trail
Here is where the 1993 flood becomes genuinely interesting for collectors of Federal Reserve notes. When the Federal Reserve retires damaged or destroyed currency and replaces it, the accounting requires precision: destroyed notes must be documented, their serial number ranges logged, and replacement notes issued. In normal circumstances, replacement notes (star notes, indicated by a star symbol replacing the final letter in the serial number) are issued when a note is damaged during the printing process and must be replaced to maintain accurate sheet counts.
In disaster scenarios, the process is somewhat different. The Fed does not reissue star notes specifically keyed to destroyed serial numbers on a one-for-one basis. Instead, emergency replacement currency is simply fresh, sequentially-numbered new currency from the BEP’s current production runs, rushed to the affected districts. The star notes of this period that carry the most collector significance are those associated with the Kansas City (J) and St. Louis (H) districts from Series 1990 runs conducted in the second half of 1993, as these represent the BEP’s production during the peak replacement window.
When hunting Series 1990 star notes from the Kansas City (J) and St. Louis (H) districts, focus on $1, $5, $10, and $20 denominations. Higher denomination notes ($50 and $100) were more aggressively tracked and retired by the Fed regardless of condition, meaning far fewer survived in collector-grade condition from this era. A Series 1990 $1 star note with a J or H district designator in Gem Uncirculated (MS-65 EPQ or equivalent PMG 65 EPQ) is a legitimate piece of monetary history from this period.
What Was Actually in Those Vaults: The Currency Composition of 1993
To appreciate what was destroyed, it helps to understand the composition of vault currency in small Midwestern banks during the summer of 1993. Federal Reserve notes in active vault stocks would have included a mix of series. The most recent large-face series redesigns had not yet occurred: the dramatic security-enhanced Series 1996 notes with enlarged off-center portraits and security threads were still three years away. Circulating currency in 1993 consisted primarily of the small-face Federal Reserve notes that had been standard since 1963.
A typical Midwest community bank vault in July 1993 would have held inventory spanning several series: Series 1985 notes (James A. Baker III and Katherine Ortega signatures), Series 1988 and 1988-A notes, and the most current Series 1990 notes. Older series from the 1970s would still have occasionally appeared in lower denominations. The $1 Federal Reserve note in Series 1988-A bearing the Chicago (G) district letter was among the most commonly circulating notes in Illinois and Wisconsin communities that sustained flooding.
The Mutilated Currency Redemption Process
For residents and bank officials trying to salvage value from flood-damaged currency, the Bureau of Engraving and Printing’s Mutilated Currency Division provided a critical service. Under long-standing Treasury regulations, the government will redeem mutilated currency at face value if the submitter can demonstrate that more than 50 percent of the original note is clearly present and identifiable. The key identification requirements in 1993 included legible denomination, visible portions of serial numbers, and enough of the note’s face to confirm its denomination and series.
The practical challenge in 1993 was extraordinary. Many notes arrived at the BEP’s Mutilated Currency Division fused into solid masses of paper, silt, and organic material. Examiners used specialized tools including dental picks, fine brushes, humidity chambers, and ultraviolet lamps to carefully separate and identify individual notes. The BEP processed flood-related mutilated currency claims from mid-1993 well into 1994, with particularly large institutional submissions coming from Iowa banks in the Des Moines metro area and Missouri River community banks.
The BEP’s Mutilated Currency Division receives approximately 30,000 claims annually even in non-disaster years. If you are a collector who acquires estate currency and encounter a brick-like mass of fused notes from a Midwestern estate, do not attempt to separate them yourself. Send the intact mass to the BEP Mutilated Currency Division at 14th and C Streets SW, Washington, D.C. 20228. They will examine and redeem what they can at face value, which may significantly exceed any numismatic value for damaged notes.
The ATM Factor: A Modern Complication
The 1993 flood was one of the first major natural disasters to severely test the ATM infrastructure of American banking. By 1993, automated teller machines had become standard fixtures at banks throughout the Midwest. Many ATMs in flood zones were free-standing outdoor units or ground-level installations that went underwater during peak flooding. Each ATM cassette typically held between $10,000 and $20,000 in $20 Federal Reserve notes in 1993, and floodwaters that infiltrated ATM cabinets destroyed the currency inside while also potentially triggering insurance claims and currency accountability questions that local Federal Reserve branches had to resolve.
The Series 1990 $20 Federal Reserve note is consequently the denomination most associated with the flood replacement effort. The $20 note bearing the H (St. Louis) and J (Kansas City) district designations from Series 1990, with higher serial number ranges indicating mid-to-late 1993 production, represents the workhorse currency of the emergency replacement effort.
Collector Significance and the Market Today
The 1993 flood does not have a dedicated catalog designation in standard reference works like the Friedberg catalog in the way that specific printing errors or variety notes do. However, the event’s numismatic legacy is traceable through several collecting strategies. First, date-coded Series 1990 notes from H and J districts in gem uncirculated condition represent the replacement currency of this disaster. Second, any surviving flood-damaged notes with documented provenance from affected institutions carry genuine historical value as disaster artifacts. Third, the concentration of Series 1990 BEP Fort Worth production destined for Midwestern districts during this window created specific serial number block concentrations that sophisticated collectors have tracked.
Auction records at Heritage Auctions and Stack’s Bowers from the past decade show that disaster-provenance currency, when accompanied by solid documentation, commands premiums of 15 to 40 percent above comparable non-provenanced examples in the same grade. A certified PMG 65 EPQ Series 1990 $20 note with J district designation and documented bank provenance from a flood-affected Missouri institution would be a genuinely uncommon item worth pursuing.

Lessons for Modern Collectors
The Great Midwest Flood of 1993 serves as a powerful reminder that paper currency is, above all else, a physical artifact subject to the full range of physical threats. For collectors, this event illuminates several underappreciated corners of the Series 1990 and late-small-size Federal Reserve note market. The H and J district designations, often overlooked in favor of the New York (B) district notes that dominate auction catalogues due to their sheer volume, carry genuine historical weight from this period.
Building a thematic collection around the 1993 flood is achievable at multiple budget levels. An entry-level approach might focus on acquiring gem uncirculated examples of all four affected districts (G, H, I, J) in Series 1990 across the major denominations, certified by PMG or PCGS Currency. An advanced collection might add documented flood-provenance examples, period newspaper clippings, BEP mutilated currency claim correspondence, and Federal Reserve district annual reports from 1993 and 1994 that reference the emergency replacement operations. At the top tier, a serious specialist might attempt to acquire an actual flood-damaged note with complete chain of custody documentation from a named financial institution in the disaster zone.
Paper money collects history in ways that coins cannot. When you hold a Series 1990 $20 note with a J district designator, printed in Fort Worth in the autumn of 1993, you may well be holding currency that physically replaced money lost to one of the most devastating natural disasters in American history. That invisible provenance is precisely what makes currency collecting endlessly compelling.
