Sunken Treasure: Spanish Doubloons off the Florida Coast

Florida has a unique connection to early U.S. Gold Dollars, particularly those minted in the mid-19th century. In this article, we explore the history of Gold Dollar coins, their circulation in Florida during the post-Territorial era, and how to spot rare Floridian die varieties.

Historical Context

Between 1849 and 1854, the U.S. Mint struck the Type I Gold Dollar (1834–1854). Many of these found their way to Florida via steamboats carrying gold rush prospectors heading for Eastern markets. By studying spending records from St. Augustine and Tampa Bay merchants, collectors can trace specific dates and mintmarks—for example, the famous 1850 “Large 0” obverse that circulated heavily in Key West.

Identifying Rare Varieties

  • 1850 “Large 0” Proofs: Extremely scarce in Florida, often sold for $5,000+ on certified platforms.
  • 1854 Classic Head (Type II): Slightly more common, but Florida specimens minted from early dies show distinctive die cracks near the date.

Market Value Today

Gold Dollar prices vary widely:

  • Common Date (1851–1853): $300–$600 (AU condition)
  • Key Dates (1850 “Large 0”, 1854 Type II): $3,000–$7,500 (MS condition)

Where to Search in Florida

  • Local Coin Shows: Miami and Orlando host annual summer shows with specialized Gold Dollar dealers.
  • Beach Metal Detecting: Panhandle beaches occasionally yield 1850s gold fragments, though finding intact coins is extremely rare.
  • Estate Auctions: Jacksonville and Tampa frequently list Floridian collections including original gold pieces.

Conclusion

For collectors seeking Florida provenance, focus on the 1850 “Large 0” and early 1854 Type II examples. Always request a letter of authenticity specifying provenance, ideally from a Florida estate or dealer specializing in Territorial-era coins.
