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.
