No Such Thing as a 500 Balboa Gold Coin from Panama

There is no 500 Balboa gold coin issued by Panama. The reason is straightforward: Panama uses the U.S. dollar as its official currency.

Panama's Monetary System

• Official currency: United States Dollar (USD) — since 1904 (dollarization).
• Local coinage: Panama mints its own centésimos (1, 5, 10, 25, 50 centésimos, 1 balboa) — same size/composition as US cents, nickels, dimes, quarters, half-dollars, dollars. They circulate interchangeably with US coins.
• Balboa (PAB): Pegged 1:1 to USD; exists only as coins. No paper balboas.
• Commemoratives: Panama has issued gold/silver collector coins (e.g., 100 balboas gold, 20 balboas silver) — but never a 500 balboa gold coin.

What You Might Be Thinking Of

• 100 Balboa gold coin (1975–76, 0.900 fine, ~1 oz) — commemorative.
• US $500 gold coin — never existed for circulation; modern $50 American Eagle (1 oz) is highest regular issue.
• Panama-Pacific $50 gold (1915) — US commemorative, octagonal/round.

If you have a "500 balboa gold coin," it's likely a fantasy piece, replica, or misidentified. Authenticate with a numismatist.
