1990-D 25C MS67 Certification #82400095, PCGS #5929
The 1990-D Washington Quarter is very common as the Mint struck them in the hundreds of millions. Only examples in MS66 appear to be somewhat scarce but still easily obtainable at a very small premium. Examples in MS67 condition are really scarce with less than a few dozen known. There is at least one known example in PCGS MS67+ condition but none have been graded higher.
