Quick answers
- Is the 1939-S Mercury Dime rare?
- No. 11 million were made, a typical run for the series. Condition and varieties decide its value, not the date.
- Is the 1939-S Mercury Dime silver?
- Yes. It's 90% silver, 10% copper and holds 0.0723 troy ounces of pure silver.
- Where is the mint mark on a 1939 Mercury Dime?
- On the reverse, to the left of the base of the fasces. Philadelphia dimes have no mint mark. On this coin the mark is S, for San Francisco.
- Which San Francisco dates near 1939 are scarcer?
- The 1938-S at 8,090,000, the 1936-S at 9,210,000, the 1937-S at 9,740,000. So the 1939-S is on the scarcer side for those years.
- How many 1939-S Mercury Dime coins were made?
- 10,540,000.
What to check on your 1939-S
- Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 1939-D (24 million made).
- Don't clean it. Cleaning leaves fine scratches and an unnatural shine that collectors avoid.
- Proof or circulation strike? A proof has mirror-like fields and frosted design details and was sold to collectors, not released in change. The 1939 Mercury Dime Proof (9,321 made) is the one to compare with.
- Judge the grade under good light. Look at the hair above Liberty's forehead and the bands across the fasces. Fully split, rounded center bands ("Full Bands") bring large premiums.
Circulated examples are usually traded for their silver content. Pick out the best ones: original luster and attractive toning lift a coin above melt, while cleaned coins lose most of their collector value.
The story of the 1939-S
Output at San Francisco climbed to 10,540,000 in 1939, from 8.1 million the year before. The next year it made 22 million (1940-S).
The other mints made far more that year: 1939 alone came to 68 million, roughly 6.4 for every 1939-S. That makes the 1939-S the scarcer 1939 coin, though still a common one.
San Francisco struck the Mercury Dime in 25 issues between 1916 and 1945. By mintage this one lands in the more common half, while the key for that mint is the 1926-S (1,520,000). Within the 1930s it's 12th smallest of 22, between the 1935-D (10 million) and the 1937-D (14 million).
Prewar abundance (1938 to 1941)
Mintages kept rising as the economy recovered and defense spending grew. Philadelphia struck 22,190,000 dimes in 1938, then 67,740,000 in 1939, 65,350,000 in 1940 and 175,090,000 in 1941. Denver and San Francisco followed the same curve, from 5,537,000 for the 1938-D to more than 43 million each in 1941. In all, the three mints made 510,413,000 Mercury dimes dated 1938 to 1941.
Proofs were struck every year, rising from 8,728 in 1938 to 16,557 in 1941. Collectors kept saving business strikes by the roll. As a result, almost every date of the period is easy to find uncirculated. The 1938-D is the scarcest of the group by mintage but is still a common coin. Strikes are generally better than in the 1920s, so full-band examples exist for every date, though the bands still vary a lot from coin to coin.
These are the dimes that most often turn up in old jars, coin folders and inherited collections. A worn piece is worth its metal value, since every one contains 0.0723 troy ounces of silver. Uncirculated coins with full bands bring a small premium or more. Silver dimes stayed in circulation until the Mint switched to copper-nickel clad in 1965, after which people pulled the old silver ones from change, so many of these coins spent only a couple of decades in use.
How to recognize it
Weinman's Liberty faces left in a close-fitting Phrygian cap with small wings, which he meant as a symbol of liberty of thought, not a portrait of the god Mercury. LIBERTY arcs over her head, IN GOD WE TRUST sits in small letters below her chin at the lower left and the date is at the lower right. His AW monogram appears between the date and the Y of LIBERTY. The reverse shows a fasces, a bundle of rods wrapped around an ax blade and tied with bands, with an olive branch for peace curling around it. UNITED STATES OF AMERICA runs along the top, ONE DIME across the bottom and E PLURIBUS UNUM at the right. The mint mark, when there is one, sits at the lower left of the fasces. The coin is 17.9 mm across with a reeded edge.
