Adding another unique aspect to the series, from 2015 onward the United States Mint produced and issued Reverse Proof Presidential Dollars (Buy on eBay). These coins were only included within special numismatic sets offered in very limited production runs.
Reverse proof coins invert the frosting pattern used for typical modern proof coins. A typical proof will display frosted raised design elements and inscriptions against a mirrored background. A reverse proof coin will display the opposite effect of mirrored raised design elements and inscriptions against a frosted background.
