Jaime Hernandez: The 1955 Proof Roosevelt Dime is fairly common up to about PR67 condition. In PR68 or higher it becomes scarce. With the Cameo designation it is somewhat scarce in PR67 Cameo and higher. With the Deep Cameo designation it is very difficult to find, with about 100 examples known more or less in all grades combined. There are no examples graded higher than PR68 Deep Cameo by PCGS.
