For long-lasting protection as well as an eye appealing display at a very reasonable price, we highly recommend these plastic holders for your Uncirculated and Proof coins that are valued at several dollars per coin and up. 

Holders are made of inert polystyrene that will not harm your coins. Two halves simply snap together virtually airtight. Holders have a frosted background and a clear window. Can be used for U.S. coins or World coins by matching the size of the holder to your specific coin. 

Will fit all coin sizes from 10 to 32 Millimeter.
