The world’s most valuable modern coin, the 1975 No S Proof Dime, will be auctioned by Great Collections on Sunday, October 27th. This extremely rare dime is one of only two discovered and has been owned by an Ohio family for over 45 years. The coin is graded PCGS Proof-67 by the Professional Coin Grading Service and approved by the Certified Acceptance Corporation (CAC). It is a prized item in the world of numismatics, regularly ranked as the top modern U.S. coin by experts.
History of the 1975 No S Proof Dime
In 1975, the U.S. Mint produced 2.84 million proof sets with the “S” mint mark, indicating they were made at the San Francisco Mint. However, two proof sets were discovered to have the 1975 Roosevelt Dime without the “S” mint mark, making them incredibly rare. Both of these sets were found in California and sold to the well-known coin dealer F.J. Vollmer in the late 1970s.
The first 1975 No S Proof Dime was sold to an Ohio collector and his mother for $18,200 in 1978, while the second was sold for $38,550 the following year. This coin will now be up for auction for the first time by GreatCollections.
Past Auction Sales and High Value
The 1975 No S Proof Dime has appeared at auction twice before. In 2011, one example sold for $349,600, and in 2019, it sold again for $456,000. Shortly after, it was purchased privately for $516,000. This makes it one of the most valuable modern coins ever sold.
