Authentication is Critical
Due to its extreme rarity, fakes are common. Be cautious of:
- Altered-date Peace Dollars (1921–1935 coins modified to read “1964”)
 - Illegal modern restrikes
 - High-grade counterfeits circulating in the numismatic market
 
Verification Checklist
- Metallurgical testing
 - Mint archive provenance
 - PCGS or NGC certification with special “1964-D Peace Dollar” label
 

Where It Might Be Found
- Forgotten private collections
 - Bank vaults with old silver dollar hoards
 - Foreign holdings shipped before 1973
 - Safety deposit boxes from estates or inheritances
 
What To Do If You Find One
- Do NOT clean or polish the coin — it will destroy the value.
 - Handle only by the edges with cotton gloves.
 - Store in a secure, climate-controlled bank vault.
 - Contact PCGS or NGC for immediate authentication.
 - Work with legal counsel and auction houses like Heritage Auctions — U.S. Treasury approval is required for sales.
