The actual value of the 1894-S Barber Coin is just ten cents, but the coin’s rarity has caused it to be sold for thousands of times that value. The S-Barber was produced in 1894 as part of the U.S. Barber coinage. It has gone on to rival the 1913 Liberty Head Nickel and 1804 Dollar as one of the highest-prized collectors’ coins.

Only twenty-four of these dimes were ever minted, and, of that number, just nine have survived. All are proof coins, and seven are heavily-worn. In 2005, one sold for $1.3 million. Two years later, the price had jumped, and one sold for nearly $2 million.
