A proof coin is a specially manufactured coin struck multiple times on hand-polished dies using specially prepared blanks, resulting in mirror-like reflective fields and sharply frosted raised designs.
Proof vs. Bullion
- Proof coins contain the same metal content as their bullion counterparts
- The difference is purely in manufacturing quality and finish
- Proof coins are packaged individually with Certificates of Authenticity
- Proof coins carry significantly higher premiums
Types of Proof Finishes
- Standard Proof: Mirror fields, frosted devices
- Reverse Proof: Frosted fields, mirror devices (the opposite)
- Enhanced Proof: Multiple finishes on different areas of the coin
Are Proofs Good Investments?
Proof coins appeal to collectors more than pure investors. Their higher premiums mean they must appreciate more to generate the same return as bullion. However, limited-edition proofs can gain significant numismatic premiums.
