The Pittman Act of 1918: How Silver Dollar Melting Led to a Surge in Silver Certificate Production

In the spring of 1918, with the United States fully committed to the Allied cause in World War I, a quiet but consequential piece of legislation passed through Congress that would permanently alter the landscape of American paper money. The Pittman Act, signed into law on April 23, 1918, authorized the melting of up to 350 million Morgan Silver Dollars and their conversion into bullion to be sold to Great Britain at $1.00 per fine troy ounce. The silver was desperately needed to stabilize the currency of British India, where a wartime silver shortage threatened economic chaos. What followed was a cascade effect: the destruction of those coins legally required the Treasury to maintain backing for Silver Certificates already in circulation, forcing a massive new print run of notes to replace the coins that had been withdrawn and destroyed. The story of the Pittman Act is, at its core, a story about how geopolitical crisis reshapes the money in ordinary Americans’ pockets.

The Mechanics of the Pittman Act

Senator Key Pittman of Nevada, a champion of Western silver-mining interests, drafted the legislation with two goals in mind. The first was immediate: provide Britain with the silver needed to mint rupees and shore up confidence in Indian colonial currency during a period when hoarding was rampant across the subcontinent. The second goal was longer-term and more self-serving for Nevada’s economy: a guarantee that the United States government would purchase domestically mined silver at $1.00 per fine ounce to replace every coin melted. This repurchase provision kept Western mining lobbies firmly in support of the bill.

Between 1918 and 1919, the Philadelphia and San Francisco Mints operated around the clock melting Morgan Dollars. Estimates from Treasury records indicate that approximately 270,232,722 silver dollars were ultimately destroyed, though some historians place the figure slightly higher when accounting for administrative rounding. The coins came primarily from Treasury vaults, where they had sat largely uncirculated since their original minting in the 1880s and 1890s. Entire date-and-mintmark combinations were wiped out or drastically reduced in surviving population, explaining why certain Morgan Dollar dates carry enormous numismatic premiums today.

Silver Certificates and the Legal Backing Problem

Here is where paper money collectors enter the picture in a meaningful way. Under the laws governing Silver Certificates at the time, every dollar-denomination certificate in circulation had to be backed by a corresponding silver dollar held in Treasury vaults. When those silver dollars were melted under the Pittman Act, the Treasury faced an immediate legal and logistical problem: hundreds of millions of dollars in Silver Certificates were suddenly without their mandated coin backing.

Congress addressed this through a provision within the Pittman Act itself, temporarily allowing the Treasury to back Silver Certificates with silver bullion rather than coined dollars during the transition period. This kept existing notes technically legal and in circulation, but it also meant the Treasury had to manage its note issuance carefully to avoid a public crisis of confidence. The Bureau of Engraving and Printing ramped up production substantially, and the years 1918 through 1923 saw some of the largest print runs of Silver Certificates in American history.

For large-size note collectors, the Series of 1899 $1 Silver Certificate, sometimes called the “Black Eagle” note, saw extended use well into the early 1920s precisely because of this production surge. The Series of 1923 $1 Silver Certificate, the last large-size $1 note ever issued, was directly born from the need to maintain adequate currency supply after Pittman Act disruptions. Friedberg catalog number Fr. 237 through Fr. 240 covers the 1923 series, with signature combinations ranging from Speelman-White to Woods-White. These notes were printed in truly enormous quantities: the Speelman-White combination alone accounted for hundreds of millions of notes, making circulated examples common but choice uncirculated specimens with bright paper and strong embossing genuinely desirable.

The 1923 $5 Silver Certificate: A Pittman Act Trophy Note

While the $1 Silver Certificate of 1923 is the most recognizable large-size note associated with the Pittman Act era, the Series of 1923 $5 Silver Certificate (Fr. 282, Porthole note) deserves special attention. Featuring a portrait of Abraham Lincoln framed in a circular vignette that gives it the “Porthole” nickname among collectors, this note was issued in relatively modest quantities compared to the $1 notes and represents one of the final expressions of large-size American currency before the transition to small-size notes in 1928.

The Fr. 282 carries the Speelman-White signatures and a blue Treasury seal. In circulated grades (Fine to Very Fine), examples trade in the $150 to $400 range depending on margins and paper quality. In Choice Uncirculated (PMG 64 or better), the note commands $1,500 to $3,500 at major auction houses, with exceptional examples graded 66 EPQ having realized over $6,000 at Heritage and Stack’s Bowers sales in recent years.

The Transition to Small-Size Notes and the 1928 Series

The Currency Act of 1928, which standardized American paper money to its current smaller dimensions, coincided almost precisely with the period when Pittman Act replacement silver was being coined into Peace Dollars (minted 1921 through 1928 and briefly in 1934 and 1935). The new small-size Silver Certificates of the Series 1928 bore the familiar blue Treasury seal and were printed in the standard 6.14 x 2.61 inch format that collectors know today.

The Series 1928 $1 Silver Certificate (Fr. 1600) with Tate-Mellon signatures is a key early small-size issue. Its print run of approximately 638,296,908 notes sounds enormous, but heavy circulation and public use means that gem uncirculated examples (PMG 65 EPQ and above) are genuinely scarce. The Tate-Mellon signature combination was short-lived because Andrew Mellon retained his position but Walter O. Woods replaced H.T. Tate in January 1928, making the Tate-Mellon pairing one of the shorter-duration signature combinations of the early small-size era.

The Numismatic Ripple Effect: Morgan Dollar Survivors

It would be incomplete to discuss the Pittman Act without acknowledging how it shapes coin collecting alongside paper money collecting. The Treasury’s mandate to replace melted coins was fulfilled through the Peace Dollar series, first struck in 1921 with a high-relief design by Anthony de Francisci and modified to lower relief in 1922. Peace Dollars struck from 1921 through 1928 were produced using silver purchased under the Pittman Act’s domestic mining guarantee at $1.00 per ounce, making every Peace Dollar from this era a direct numismatic artifact of the same legislation that reshaped Silver Certificate production.

For the paper money collector, the practical takeaway is this: the Pittman Act created artificial scarcity in Morgan Dollars (driving up their numismatic value), necessitated a massive surge in Silver Certificate production (creating abundant large-size notes from 1918 to 1923), and ultimately contributed to the smooth transition to small-size currency in 1928 by stabilizing silver reserves. It is one of the cleanest examples in American monetary history of how a single piece of legislation creates ripple effects that numismatists are still tracing more than a century later.

Building a Pittman Act Themed Collection

One of the most rewarding ways to engage with this history as a collector is to build a thematically focused set. A Pittman Act collection does not need to be exhaustive or expensive. At its core, you might aim for three anchors: a large-size Silver Certificate from the 1899 or 1908 series predating the act, a 1923 large-size note representing peak Pittman-era production, and an early small-size Silver Certificate from the 1928 series representing the post-act stabilization period. Supplementing these with a circulated Morgan Dollar from a heavily melted date and a 1921 or 1922 Peace Dollar ties the paper money story directly to the coin story in a way that is both visually compelling and historically complete.

Dealers specializing in large-size type notes are the best starting point for the 1899 and 1908 issues. For the 1923 $1, raw circulated examples appear constantly at coin shows and on major auction platforms, and buying a PCGS or PMG graded example in the 30 to 45 range is a cost-effective entry point. The Porthole $5 of 1923 requires more patience and budget but is not beyond reach for a determined collector willing to monitor Heritage Auctions and Stack’s Bowers on a quarterly basis.

The Pittman Act of 1918 stands as a reminder that American paper money is never just paper. It is a document of economic policy, wartime necessity, political compromise, and the daily anxieties of an earlier America. Every Series 1923 Silver Certificate that passes through a collector’s hands once circulated through an economy still absorbing the shock of a war that melted hundreds of millions of silver dollars into bullion and shipped them across an ocean. That context does not reduce a note’s grade or its technical rarity, but it does add something no grade can capture: genuine historical weight.
