The 1916 Mercury Dime

Known as one of the rarest U.S. coins, only 24 of these dimes were minted in San Francisco. Of those, only a handful are known to exist today. In pristine condition, this dime can sell for over $1 million at auction, making it a collector’s dream.

Introduction to the 1916 Mercury Dime

• The 1916 Mercury Dime is one of the most iconic and valuable dimes in American numismatics.
• It was designed by Adolph A. Weinman and features the winged Liberty head, which gives the coin its “Mercury” nickname (though it represents Liberty, not the Roman god).

Historical Context

• Minted in 1916, the Mercury Dime was part of a series of new coin designs introduced as part of a major overhaul of U.S. coinage.
• This coin replaced the previous Barber Dime, which had been in circulation since 1892.
• It was the first U.S. dime to feature a design that was considered more modern and artistic for its time.

Design Details

• Obverse: Features Liberty’s head with a winged cap, symbolizing freedom of thought and action.
• Reverse: Shows a fasces (a bundle of rods symbolizing strength) and an olive branch (symbolizing peace), with the word “One Dime” and a mintmark at the bottom.
• The coin has a diameter of 17.9 mm and weighs 2.5 grams.

The 1916 Mercury Dime’s Value

• The 1916 Mercury Dime is highly sought after by collectors due to its scarcity and iconic design.
• In circulated condition, the value can range from around $10 to $30, depending on the coin’s wear and condition.
• Uncirculated or high-grade versions, especially those with mint errors or rare features, can fetch much higher prices — up to $100,000 or more.
• The 1916-D Mercury Dime (minted in Denver) is considered even rarer and more valuable than the 1916 without a mintmark.

Key Variations and Rarity

• 1916-D Mercury Dime: The 1916-D is the most valuable in the series due to its low mintage. Only about 264,000 were produced, making it a highly coveted coin for serious collectors.
• 1916 No Mintmark: The Philadelphia-minted version of the 1916 Mercury Dime, while not as rare as the 1916-D, is still valuable and sought after, especially in high-grade condition.

S Barber Dime 1894

This is one of the most sought after dimes in a collection; that D mintmark indicates its being produced at Denver. Mint condition dimes sell for upwards of $100,000, but even worn examples sell for thousands.

Introduction to the 1894-S Barber Dime

• The 1894-S Barber Dime is one of the rarest and most valuable coins in U.S. numismatics, with only 24 known to exist.
• It is famous for its extreme rarity, unique minting history, and high market value, often exceeding $1 million in certain grades.

Historical Background

• The Barber Dime series was designed by Charles E. Barber, Chief Engraver of the U.S. Mint, and was produced from 1892 to 1916.
• The 1894-S Barber Dime is particularly famous because of its mysterious low mintage and unique historical context.

Minting Details

• Minting Location: The coin was struck at the San Francisco Mint (S mintmark), in 1894.
• Only 24 coins were minted, though their intended purpose is unclear. It is believed that these dimes were struck as part of an unofficial batch, potentially for personal use or for a specific private purpose by the Mint director.

Design of the Coin

• Obverse: Features Lady Liberty wearing a cap, designed by Charles E. Barber. The inscription “LIBERTY” is above, with “UNITED STATES OF AMERICA” and “E PLURIBUS UNUM” on the outer rim.
• Reverse: Shows a wreath of olive and laurel leaves surrounding the denomination “ONE DIME” with a small mintmark “S” underneath the wreath.
• The Barber Dime has a diameter of 17.9 mm and weighs 2.5 grams.

Rarity and Value

• The 1894-S Barber Dime is the rarest coin in the Barber Dime series. Due to its tiny mintage of just 24 coins, it is extremely sought after by collectors.
• Market Value: The 1894-S Barber Dime regularly sells for upwards of $1 million in auction for coins in excellent condition, with some examples reaching even higher values depending on the grade.

1968 No-S Proof Dime

Proof dimes are produced for collectors and typically feature an “S” mint mark for San Francisco. However, some 1968 dimes were accidentally produced without the mark, making them extremely valuable. A No-S Proof Dime can sell for over $20,000 depending on the condition.

Introduction to the 1968 No-S Proof Dime

• The 1968 No-S Proof Dime is one of the most famous and sought-after coins in U.S. numismatics due to its unique error: it was struck without the “S” mintmark, which indicates that it was produced at the San Francisco Mint.
• This rare coin is a mistake from the U.S. Mint and has become a collector’s item because of its unexpected and uncommon nature.

Historical Context

• Proof coins are specially struck for collectors, often with higher quality and finer details than regular circulating coins. They are usually minted with a mirror-like finish.
• In 1968, proof dimes were supposed to have the “S” mintmark, indicating they were struck at the San Francisco Mint. However, a handful of these dimes were struck without the “S” mintmark, making them highly valuable today.

The Error: No “S” Mintmark

• Normally, proof coins produced at the San Francisco Mint have the “S” mintmark, placed below the “UNITED STATES OF AMERICA” inscription on the reverse of the coin.
• In the case of the 1968 No-S Proof Dime, a small number of coins were mistakenly struck without this mintmark, making it a minting error.
• It is believed that the die used for the proof coins may have been prepared incorrectly or that an error occurred during the production process, leading to the omission of the mintmark.

Design of the Coin

• Obverse: Features Franklin D. Roosevelt’s portrait, designed by John R. Sinnock, who was the Mint’s Chief Engraver.
• Reverse: Shows a torch, olive branch, and oak branch, symbolizing liberty, peace, and strength, with the denomination “ONE DIME” displayed, as well as the mintmark (or lack thereof in this case).
• The 1968 Proof Dime, including the No-S variety, has a diameter of 17.9 mm and weighs 2.5 grams.

Rarity and Value

• The 1968 No-S Proof Dime is rare due to the limited number of coins minted without the “S” mintmark.
• It is estimated that only around two dozen examples of the 1968 No-S Proof Dime exist today, and most of these are in excellent condition.
• The coin’s value can vary significantly based on its condition and the market, with well-preserved examples often commanding prices in the thousands of dollars. In Mint State (MS) or PR (Proof) 68 or higher, these coins can be worth between $20,000 to $40,000 or more at auction.

Mercury Dime Overdate Error 1942/41

This error coin, where the years 1941 and 1942 are visible on both sides, is highly collectible and very rare. A high-grade example like this could bring $10,000 to $30,000.

Introduction to the 1942/41 Mercury Dime

• The 1942/41 Mercury Dime is a notable overdate error in U.S. numismatics, where the year “1942” was struck over a previous year’s die that was stamped with “1941.”
• This overdate error makes the coin a rare and valuable collector’s item, as it was the result of a mistake during the minting process.

Historical Context

• The Mercury Dime series, which ran from 1916 to 1945, is one of the most popular and iconic U.S. coin designs. The obverse features a winged Liberty, designed by Adolph A. Weinman, while the reverse shows a fasces, a symbol of strength.
• In 1942, the U.S. Mint began producing dimes for circulation with the year “1942,” but a small number of dimes were struck using leftover 1941-dated dies. This led to the creation of the 1942/41 Mercury Dime, where the “1” of “1941” can still be seen beneath the “2” in “1942.”

Minting Error: Overdate

• An overdate occurs when a new die is created but accidentally used with an old die from the previous year still in place. In the case of the 1942/41 Mercury Dime, the Mint used a die from 1941 that was not fully replaced, resulting in the year “1942” being struck over “1941.”
• The error is visible when closely examining the date on the obverse of the coin, where the “1” from “1941” can be seen under the “2” in “1942,” making it a classic overdate error.

Visual Characteristics

• Obverse: The main feature of the 1942/41 Mercury Dime is the overlapping numbers in the year “1942.” The “1” from “1941” is visible beneath the “2,” which creates the overdate error.
• Reverse: The reverse design of the coin is the same as any other Mercury Dime from 1942, with the fasces (bundle of rods) and olive branch design, along with the words “UNITED STATES OF AMERICA” and “ONE DIME.”

Rarity and Value

• The 1942/41 Mercury Dime is considered one of the most sought-after errors in U.S. coin collecting, with only a small number of coins struck with this overdate.
• It is believed that only around 25,000 to 100,000 of these error coins were made, which makes it quite rare and valuable.
• The value of a 1942/41 Mercury Dime depends on its condition, with coins in higher grades (like MS65 or PR65) fetching higher prices. In good condition, the coin can range from around $500 to $1,000, while coins in mint state or higher grades can sell for much more, with some reaching over $20,000 at auction.
