The San Francisco mint opened in 1854 and it made gold coins up through 1930. I have seen more interest in San Francisco gold coinage in the last five-ten years than I have at any other time in my numismatic career, and I feel that San Francisco gold coinage is an especially fascinating segment of the market.
If I had to select the Most Popular Branch Mint it would likely be Dahlonega. These gold coins have become an avidly-sought after area of the market with collectors from all over the country building sets...
The decision to collect this series should not be made lightly as Liberty Head double eagles have the distinction as being among the most difficult and longest-lived series in all of 19th/early 20th century American numismatics.
