The Difference Between a Proof Set and a Mint Set

Types

• Proof sets are collections of high-quality coins assembled specifically to sell to collectors. Mint sets are "one-each" collections of coins, straight from a particular minting facility, that are also designed to be sold to collectors. "One-each" sets are collections of one of each denomination of coin.

Features

• Coins included in a proof set have been created to a higher standard than those meant for circulation. They are usually very highly polished and stamped in such a way that the raised portions create a "cameo" effect. Mint set coins are simply those coins that could be circulated, but are diverted for collectors.

Potential

• Valuation of mint sets and proof sets is dependent upon a number of factors, including condition of the coins and rarity of the issue.

Fun Fact

• The U.S. Mint has produced specialty proof and mint sets over the years, including the "state quarters" and dollar sets honoring American presidents.

Time Frame

• Proof sets have been in existence, on and off, since the 1800s. Production picked up in the mid-20th Century, when coin collecting became more popular.
