The 2015-P "Reverse Proof" Roosevelt Dime is the first reverse proof dime ever made for the Roosevelt dime series. This coin was produced as part of a 3-coin "March of the Dimes" set to commemorate the 75th anniversary of the March of Dimes Foundation - which was founded by President Franklin D. Roosevelt. The 3-coin set included a Proof Silver Dollar - 2015-P Reverse Proof Dime & 2015-W Proof Dime.

The reverse proof was produced at the Philadelphia Mint using a highly innovative and technologically advanced minting process - which resulted in a coin with a frosty satin background field (like normal uncirculated dimes) but the details and designs have brilliant mirror-like features. This dime is also contains 90% silver. Only 75000 sets were authorized to be produced and originally sold for $61.95 starting on May 4 2015. This set is wildly popular and was completely sold out only days after it become available to the public.
