Mint Proof Sets vs. Mint Silver Proof Sets

Mint Proof Sets and Mint Silver Proof Sets do have many commonalities, so it’s easy to become confused between the two. There are a few key differences, which may vary with the year of the set issued. For example, for the 2002 year, the US Mint issued Mint Proof Sets as well as Silver Proof Sets. In general, both sets undergo the same proof production process. The 2002 Mint Proof Sets and Silver Proof Sets contain the same number of coins. The 2002 Mint Proof Set uses metal alloys identical to the ones used for general circulation. However, the 2002 Mint Silver Proof Sets use a 90% silver alloy in their production process.
