Following several years of low demand, the United States Mint’s practice of striking and offering Proof coins for collectors ended in 1916, only to resume in 1936 to raise money for the Treasury Department. Numismatist Roger W. Burdette writes in his authoritative United States Proof Coins: 1936-1942 (2016), that it was Louis Howe, an advisor to President Franklin Roosevelt, who pushed for the program’s return after his first idea, offering some of the gold coins in the Treasury’s possession to collectors at a premium, was rebuffed.

According to Burdette, the first 1936 Proof to be struck was a Washington Quarter, presented to Howe shortly before his death on April 18. Howe must have been pleased with the specimen because Treasury Secretary Henry Morgenthau, Jr. ordered the Mint to go forward with Proof coinage on April 16.

The 1936 Mercury Dime Proof was one of five Proof coins issued in 1936. Along with the dime, the complete set included the 1936 Walking Liberty Half Dollar Proof, the 1936 Washington Quarter Proof, the 1936 Buffalo Nickel Proof, and the 1936 Lincoln Cent Proof. These coins were sold individually, with a surcharge added to the cost of each coin plus postage. The surcharge for the 1936 Mercury Dime Proof was set at 10¢; the larger but less valuable 1936 Buffalo Nickel Proof carried a surcharge of 15¢! A total surcharge of 90¢ was required for the purchase of one example of all five denominations.

Demand for the 1936 Proofs, while minuscule by today’s standards, was considerably higher than any other Proof issue released to that point in the 20th century, and demand would increase each year from 1936 to 1942. Several factors contributed to this.

For starters, the coin-collecting hobby was growing, not just among the elite but among the working class. Despite the hardship of the Great Depression, Americans found some enjoyment in filling penny boards.

Secondly, interest in Proof issues had continued despite the Mint’s suspension of the program, and each year the Mint fielded letters from collectors inquiring about Proof coins.

And finally, the commemorative coin craze reached its crescendo in 1936. Collectors and speculators charted the course for the modern coin market by lobbying Congress to support their pet projects with the issuance of commemorative half dollars (or entire series of them). Many of these collectors were motivated to ride their hobby even further by purchasing the annual Proof issues.

1936 Proofs: A Tale of Two Finishes

The Mint was deficient in experience when it came to producing Proofs of the quality that numismatists had come to expect. Despite being offered as “perfect coins” struck on “highly polished planchets,” Proofs sold early in the year exhibited a satin finish. This disappointed some, leading the Mint to face public scrutiny in the pages of The Numismatist, primarily concerning the satin finishes found on the Lincoln Cent and Buffalo Nickel Proofs.

The silver coins were struck in a brilliant finish that would become more distinctive as the Mint continued to improve its planchet and die preparation methods.

Burdette reports 14 deliveries of Proof Mercury Dimes for 1936, with most of the deliveries occurring before July 14. These deliveries do not represent the total number of coins struck, however, as records concerning later Proof issues indicate a rejection rate of about 20%, due to quality considerations.

Subtracting 25 coins held back for Assay, the United States Mint struck and sold 4,105 1936 Mercury Dime Proofs and earned $41,050 in revenue from their sale.

Walter Breen claims that no less than eight examples were struck with a satin finish.

Choosing Which 1936 Mercury Dime Proof to Buy

The combined certified population of 1936 Mercury Dime Proofs at CAC, NGC, and PCGS as of July 3, 2024, equals 3,055 pieces – just shy of 75% of the total distributed mintage. CoinWeek assumes that some percentage of this figure consists of crossovers and upgrades where the old certification number was not removed from the dataset. This percentage is likely small and does not change the fact that most Proofs of this period have been submitted for encapsulation over the past 35+ years. The certified data shows that the typical state of preservation for the 1936 Mercury Dime Proof is Proof 65, with a nearly equivalent but smaller cohort of coins grading Proof 64 and Proof 66.

Given the subdued eye appeal of some of the most highly-preserved examples, it is clear that age and storage media have not treated these coins kindly. Coins with attractive eye appeal in the grades of Proof 65 and above should therefore command higher prices than similarly graded coins with mottled toning.

But what does premium eye appeal mean for an issue that usually has a washed-out or slightly dull appearance? The answer will differ from collector to collector.

Some adhere to the philosophy that all toning detracts from the coin’s original character. We have not personally seen a 1936 Mercury Dime Proof with fully white mirrored surfaces that hasn’t been dipped at some point. For these, we advise buying coins that still have life on the surface and no evidence of residue from the non-abrasive solution used to preserve them.

Others may find excitement in toned examples. Here, be advised that not all toning is treated the same by the market. A coin must have dazzling color characteristics to appeal to collectors of toned coins. Obverse toning is more important, but to stand out, the coin must present well in photographs and in person. Avoid coins with mottled brown toning, fingerprint stains, or copper spots in focal areas.

An attractive Proof 65 graded by a leading service will likely retail for $1,350 to $1,500. The price per coin increases dramatically with each incremental step up in grade. Coins in the Proof 68 range have approached $30,000 in recent auctions. We recommend that you avoid coins graded lower than 65 as they do not present good value for money.

Sculptor Adolph A. Weinman’s design features Liberty (of Thought) facing to the left. A winged cap adorns her head. Tufts of hair curl around the base of the cap on her forehead and behind her ear. A braid of hair wraps around the base of her neck. The word LIBERTY wraps around the top of the coin with letters spaced apart.

The letters E and R are partially obstructed by Liberty’s cap. The designer’s monogram (a “W” surmounting an “A”) appears behind Liberty’s neck below and to the left of the Y in LIBERTY. The date 1936 appears below the bust truncation to the rear. A subtle basin creates a dish-like appearance in the field.


In the center of the reverse of the 1936 Mercury Dime Proof is the fasces, a symbol of governmental authority used by the ancient Romans. An axe blade faces to the left. A curvilinear branch of olive leaves wraps behind the fasces. Wrapping around the top of the design is the legend UNITED · STATES · OF · AMERICA. Wrapping around the bottom of the design is the denomination ONE DIME. Two five-pointed stars separate the legend from the denomination. The motto E PLURIBUS UNUM (“Out of Many, One”) appears to the right of the fasces, slightly below center.


The edge of the 1936 Mercury Dime Proof is reeded.


Adolph Alexander Weinman was born in Germany and immigrated to the United States as a teenager. He studied and worked under such famous American sculptors as Augustus Saint-Gaudens and Daniel Chester French. Weinman is responsible for two of the most iconic coin designs in U.S. history: the Mercury or Winged Liberty Dime and the Walking Liberty Half Dollar, both of which debuted in the annus mirabilis numismaticus of 1916. Weinman’s sons also became sculptors and coin designers, and he taught such pupils as Anthony de Francisci. Adolph Weinman died in 1952.
