The Survival Estimate represents an average of one or more experts' opinions as to how many examples survive of a particular coin in three categories: 1) all grades, 2) 60 or better, and 3) 65 or better. These estimates are based on a variety of sources, including population reports, auction appearances, and personal knowledge. Survival estimates include coins that are raw, certified by PCGS, and certified by other grading services.

The 1957 Proof Quarter is very scarce displaying Deep Cameo surfaces. And one of the tougher dates to display Deep Cameo from all the Proof Washington Quarter series. PCGS has graded less than 100 examples in all grades combined with Deep Cameo surfaces for this date. In PR68 Deep Cameo there are probably less than 50 examples that exist. In PR69 Deep Cameo it is very likely that less than a dozen examples have survived with no examples existing in better condition.
