This 2009-S Presidential Dollar 4-coin Proof Set contains four United States $1 coins struck in copper with a manganese-brass clad finish. Each coin is dated 2009 and bears the “S” mint mark, indicating it was minted at the San Francisco Mint, and the set is described as Superb Brilliant Proof, highlighting its sharply struck details and mirrored proof surfaces.

The coins are part of the Presidential $1 Coin series, a modern U.S. dollar series minted from 2007 through 2016. As a proof set, this four-coin group was made specifically for collectors rather than for everyday circulation, which adds to its desirability. Dated 2009, this set comes from the late-2000s era, during the Great Recession, and it appeals to collectors who build complete Presidential Dollar Sets, seek premium proof-quality examples, or collect modern U.S. Mint issues in original multi-coin formats.
