The 1952 Proof Washington Quarter is somewhat common and affordable in low grades that just about anyone can afford an example. It starts to become more expensive in grades of PR67 and higher. The highest known examples are in PR68 condition. In Cameo it becomes much scarcer especially in PR67 and PR68 Cameo. In Deep Cameo it is really scarce and one of the scarcer issues in the Proof Washington Quarter series. Less than a few dozen examples in all grades combined have obtained a Deep Cameo designation at PCGS.
