How Barber Lost to Weinman

Mint officials in 1915 were operating under a misapprehension. They believed the Mint Act of 1890 required them to change coin designs at the 25-year mark; in fact the statute only authorized them to do so. At Mint Director Robert W. Woolley's suggestion, the Commission of Fine Arts chose three sculptors to submit designs: Adolph A. Weinman, Hermon A. MacNeil, and Albin Polasek. Woolley intended each sculptor to design one denomination. Weinman submitted for both the dime and the half dollar, and both were chosen.¹ Charles Barber, Chief Engraver since 1880, had submitted the Mint's own designs for the new dime. They were passed over for an outsider's work. He had designed the coin being replaced, and that did not change the outcome. The Commission of Fine Arts had already rejected Barber's sketches before the outside sculptors were chosen.

Weinman understood how to work small. Seventeen and nine-tenths millimeters, enough for a portrait, the legend LIBERTY, the motto and a date, with open field left around the head. His Liberty faces left in a Phrygian cap fitted with large upswept wings. Mercury, the male god of commerce, wore a brimmed traveler's hat, the petasus, with wings on it and on his sandals. Weinman's wings were meant to suggest freedom of thought. The public saw Mercury anyway, and the name attached within months of the coin's October 1916 release. The Mint's own name for the coin, the Winged Liberty Head dime, never displaced the nickname.

A Portrait Nobody Claimed

Weinman never publicly identified his model for the obverse. A draft by Mint Director Woolley records that Weinman declined to name the model. During Weinman's lifetime, no woman came forward to say the face was hers. The identification of Elsie Kachel Stevens, wife of the lawyer and poet Wallace Stevens, who rented an apartment from Weinman with her husband from 1909 to 1916, rests on a 1913 portrait bust Weinman sculpted of her and on the facial resemblance between that bust and the dime's Liberty, a resemblance researchers have found persuasive without being able to confirm it.² Treat the attribution as traditional rather than documented.

The reverse symbolism Weinman did explain, in a 1916 statement: a Roman fasces, a bundle of rods bound around a battle-ax, which he said symbolized the strength that lies in unity, with the ax standing for preparedness to defend the Union and the surrounding olive branch for the nation's love of peace.³ In October 1916 that juxtaposition carried obvious weight, with American entry into the European war less than six months away. By the early 1930s, Mussolini had made the fasces the emblem of Italian fascism and stamped it on his movement's name. Editorial writers in the United States began pointing at the dime's reverse with varying degrees of alarm. Defenders of the design replied that the fasces stood for unity and had appeared on the dime before Mussolini's movement adopted it in 1919, and the design was not changed.

Denver Had One Delivery

Philadelphia struck 22,180,080 dimes in 1916. San Francisco struck 10,450,000. Denver struck 264,000. It is the only date in the entire series with a mintage below one million, and the only date whose absolute scarcity constitutes a genuine financial obstacle for a date-set collector rather than merely a grading challenge. The gap is the product of a specific order. In November 1916, Mint Director Friedrich von Engelken directed Denver to suspend dime production and devote its press capacity to a large quarter order.⁴ All 264,000 pieces came from a single delivery in November 1916. Most of them circulated. Collectors in the region rarely saved them when new, and most surviving 1916-D dimes are worn. Of the 264,000 struck, only a small fraction survive in Mint State.

The 1916-D is the most counterfeited Mercury dime. Standard practice is to add a D mint mark to a common 1916 Philadelphia coin; other fakes include struck counterfeits, genuine dimes with altered dates, and replicas with the COPY stamp removed. On a genuine 1916-D the D sits to the left of the base of the fasces, and the four known genuine mintmark positions and shapes are documented in reference templates. An added mintmark almost always shows tooling disturbance in the adjacent field under a loupe. Some dangerous examples require comparison under raking light against certified coins. No unslabbed 1916-D should change hands at key-date prices without PCGS or NGC authentication.

What the Bands Actually Measure

Three pairs of horizontal bands bind the fasces on the reverse. On a coin struck with properly spaced dies, each pair resolves as two discrete lines with a visible gap between them, the configuration both PCGS and NGC designate Full Bands (FB). On a coin struck with dies set fractionally too far apart, the bands merge into single blurred ridges. Under a 10x loupe the difference is usually obvious. When it isn't obvious, you have a different kind of problem.

Bowers noted what Lange had established earlier: striking pressure in this era was essentially constant, making "weakly struck" a misleading shorthand for what is actually a die-spacing issue.⁵ A coin with flat bands may never have had separated bands. Distinguishing post-mint friction from production weakness is the central grading judgment in the series, and I'd argue it's the thing that separates a working knowledge of Mercury dimes from a superficial one. Get that distinction wrong and you will consistently overpay for numerically graded coins that aren't what the label implies, and miss the ones that are.

The practical consequence: Full Bands examples of dates known to chronically under-strike, primarily 1925-D, 1926-S, and 1927-D, sell for a multiple of the price of a non-Full Bands example at the same numerical grade. A 1926-S Mint State 65 and a 1926-S Mint State 65 Full Bands are not the same coin. They share a numerical grade, and only the second has the separated bands the market pays for.

1921 and 1921-D: Circulated Before Anyone Noticed

Philadelphia struck 1,230,000 dimes in 1921; Denver struck 1,080,000. Neither figure is remotely comparable to the 1916-D's situation. With more than a million struck at each mint, these dates are not rare in absolute terms. What these dates have is a survival problem, which is a different thing and harder to see coming. The postwar recession meant that almost nobody with disposable income was putting Mercury dimes away in 1921. The coin hobby was smaller than it would become; roll accumulation was not yet established practice. When economic conditions improved, the 1921 and 1921-D had already spent years in commercial pockets and cash drawers. By then it was too late. Heritage sales from 2023 to 2025 saw the 1921-D in PCGS Mint State 65 Full Bands bring between $5,520 and $9,000, for a coin with a mintage north of a million.⁶ Those prices reflect how few were saved in 1921.

The 1942 Overdates and the Denver Coin Reported Late

Two overdates exist in the series, both dated 1942. On the Philadelphia coin the residual 1 from a prior hub impression is sharply visible beneath the 2 in the date; on the Denver issue the same undertype is present but softer, requiring closer examination. Both arose from the Mint's hub-die preparation method of the era, which required two hub strikes per working die: when a 1941-dated die received its second impression from a 1942 hub, the date conflict became permanent in the steel.

The Philadelphia 1942/1 was recognized while the coins remained in commerce, and some uncirculated examples were set aside once collectors understood what they had. The Denver issue went unreported until November 1960, when a collector in West Baldwin, Maine, described it in The Numismatic Scrapbook Magazine, and it became widely known after Delma K. Romines publicized it in 1962.⁷ Collectors did not save rolls of a variety they did not know existed. By the time the variety was reported, every Mint State 1942/1-D in existence was already sitting in someone's 1942-D accumulation, waiting to be found by someone willing to go through coins one at a time. That is the only way they surface.

Gaps, Depression Dates, and What Mintage Figures Miss

No dimes were struck in 1922, the first gap year since 1826. It followed the low mintages of 1921, and production returned in force in 1923, when Philadelphia struck 50,130,000. By 1930 the Depression had arrived; production fell sharply in 1930 and 1931, and both 1932 and 1933 saw no dimes from any mint.

The Depression-era low-mintage dates (1930-S, 1931, 1931-D, 1931-S) are not rare, and understanding why is probably more useful than knowing the mintage figures. Cardboard coin boards, first sold by J. K. Post early in 1935 and taken over by Whitman later that year, reached variety stores in the mid-1930s, and the Mercury dime was among the series they covered. Collectors pulled these dates from circulation deliberately. The 1931-S was not released until 1934, and collectors then set aside enough Mint State pieces to meet later demand. Collectors had not done the same with the 1921 issues a decade earlier. The 1931-S had a mintage of 1,800,000. It is not a key date. The 1921 had a mintage of 1,230,000. It costs more than ten times as much in Gem (Mint State 65 or finer). The difference comes from how many were saved when new.

Proofs were struck at Philadelphia from 1936 through 1942, with annual totals ranging from 4,130 to 22,329. Most of the specialist literature treats them briefly and prices them modestly, which has always seemed wrong to me. The 1936 Proof in particular is rare with deep cameo contrast, and it is priced below many coins of comparable rarity.⁸ Mercury dime Proofs with genuine cameo contrast are undervalued. They have been undervalued for years. The market for them is thin because most collectors approach the series through circulated date sets or Mint State Full Bands collections and never look at the Proofs carefully. Buyers who can recognize cameo contrast can still find these coins priced like ordinary Proofs.

The series ended in 1945 when Franklin Roosevelt died in April of that year; Mercury dimes continued to be struck in large quantities through the end of 1945, and the dime had been in production long enough that no congressional authorization was needed for a design change. Chief Engraver John Sinnock's Roosevelt portrait replaced Weinman's design starting in 1946. Total Mercury dime output over thirty years was 2,677,232,488 pieces, per the Annual Report of the Director of the Mint for 1946.⁹ Weinman's design was better than its successor. The judgment is subjective, and many specialists in both series share it.

Building the Set

Seventy-seven date-and-mint combinations, overdates aside. Common dates from 1934 through 1945 are accessible in Extremely Fine to lower Mint State for a few dollars apiece; the silver content provides a floor that makes accumulation feel rational independent of numismatic premium. Late-date Full Bands sets have become a natural first specialization for collectors who want a genuine challenge without the expense of the pre-1930 material, and it's not a bad place to start. You learn the bands standard on coins where mistakes are cheap before you apply it to the dates where they aren't.

Moving earlier, the budget rises and the search takes longer. Branch-mint issues from 1916 through 1929 require searching in any grade and carry large premiums in high grades. The 1916-D, 1921, and 1921-D are the three significant financial obstacles for a complete circulated set. A complete Mint State Full Bands set is a project measured in years, demanding selective buying, current market prices for the chronically weak-striking early dates, and frankly a willingness to pass on coins that look close but aren't. Lange's Complete Guide provides the die-variety and strike-characteristic documentation that makes working at this level possible rather than arbitrary. Most collectors who skip it eventually buy something they shouldn't have.
