1978 25C MS67 Certification #13098825, PCGS #5904
The 1978-P Washington Quarter is fairly common and in circulated grades it should be fairly easy to find in circulation. In Uncirculated grades it might be a little more challenging but some may still be found with a lot of searching. In MS65-MS66 condition it is probably best to find examples already graded as they can be purchased for a small premium. In Ms67 condition they are scarce with less than a hundred examples graded by PCGS with none being graded in higher condition.
