What this coin is
The Panama-Pacific Octagonal $50 (1915) is a gold coin of the United States. This page is for the type × composition — every date and mint of this issue has the same metal if the weight and fineness match the spec below. Melt is that metal times today’s spot, not a collector or dealer bid.
What is written on the coin
Read the denomination, the date, and the country name on the coin. People often search the words actually stamped on the piece (for example DOS PESOS or VEINTE PESOS on Mexican gold). Those words are indexed on this site.
Metal content (the melt spec)
Mint specification: 83.7550 grams at 90.17% fine, which is 2.42800 troy oz of pure gold (AGW). Formula: grams × fineness ÷ 31.1034768. Date and mintmark do not change that number. Melt today is $10,699.71 per coin at $4,406.80 gold.
Mintage
Mintage varies by date. We do not publish a year-by-year mintage table here because melt is the same for this composition. A scarce date or a high grade can be worth more than melt; a common worn piece is often near melt.
A little history
This listing is a gold-library type used by coin shops. Confirm the name on the coin matches this page before you use the melt figure.
How to tell you have this type
Match denomination, metal color, and date range. If two compositions share a design (for example 90% vs clad), the date or the edge (solid silver vs copper stripe) decides which page to use.
Date and mintmark do not change the metal on this page. Collector value is a different market — see Sold Comps for sold prices.
Before you sell
Often sells above melt
A worn common commem can sit near melt. A nice original piece often brings a collector premium. Check solds before melting the number in your head.
Melt is the metal floor. For auction and eBay solds on the same type, see Sold Comps. We list 355 melt values; collector premiums are a different market.
