1973 25C MS66 Certification #18440297, PCGS #5891
The 1973 Washington Quarter is easy to obtain in all circulated grades and even up to about MS65 condition. In MS66 it is somewhat difficult to find but if enough searching is done, examples can be found in rolls, bags or in mint sets. In MS67 condition it is very scarce with few examples known. There are no examples confirmed higher than MS67 but it's possible that a few may turn up, as more rolls, bags and mint sets are searched.
