P. Scott Rubin: The Proof Gold Dollar of 1875 is a very rare coin in a year of rare gold Philadelphia Mint issued coinage. With a mintage of only 20 Gold Proof Sets this would make it a difficult year to collect.
Confusing the issue of how many 1875 Proof Gold Dollars were available to collectors was pointed out by David Akers, who noted that for many years a number of the circulation issue coins were believed to be Proofs. This was because at only 400 minted a number of the survivors were first strike proof-like coins.
To highlight Aker’s point of view from the 1880’s until the 1950’s the availability of 1875 Gold Dollars showed a two to one ratio with more Proofs sold at auction then circulation strikes. By the 1960’s they were about evenly available, but since then the numbers reversed themselves and the ratio is now four to one with the circulation strikes more available then the Proofs.
It would seem that by the 1970’s dealers and collectors alike had learned how to differentiate between an 1875 Gold Dollar struck as a Proof and one struck for circulation. Aker’s points to the discovery that circulation strikes have a spike coming off the neck of Liberty as the easy way to tell the difference.
