Each set currently includes the following coins, each bearing the “S” mint mark of the U.S. Mint at San Francisco:

• Current Annual Quarters
• Native American $1 Coin
• Kennedy half dollar
• Roosevelt dime
• Jefferson nickel
• Lincoln penny

Unlike circulating coins, proof coins display mirror-like backgrounds with frosted, sculpted foregrounds. Proof coins receive the highest quality strikes and can be distinguished by their sharpness of detail and shiny surface. The coins are placed in presentation lenses to showcase and preserve their exceptional finish.

The quarters, half dollar, and dime are struck in 99.9% fine silver.
