United States Proof Sets are unique items that were first produced in 1936 with a very limited release.  Proof coins refer to the method of production and not the finish of the coins although proof coins usually are distinguished by their mirror like surfaces.

Each set contains:

• Lincoln cent 
• Jefferson nickel
• Roosevelt dime
• American Women Quarters - Pauli Murray, Patsy Mink, Mary Walker, Cella Cruz and Zitkala-Ša
• Kennedy half
• Sacagawea dollar
