San Francisco "Twenty Coin" 1854: Myth or Mistake?

No such coin exists. Two facts clarify the confusion:

1. The San Francisco Mint opened in April 1854—its first coins were gold dollars, $2.50, $5, $10, and $20 pieces dated 1854-S.
2. The $20 gold piece (Double Eagle) was authorized in 1849 and first struck in Philadelphia in 1850. San Francisco began minting them in 1854.

An "1854-S Double Eagle" is real and highly collectible (mintage: 141,468). But a "San Francisco twenty coin from 1854" as a unique type? No. It's simply the first year of Double Eagle production at the SF Mint.
