Hello,
I may not be an expert at grading but I did learn a little bit about this exact same coin some time ago from some more experienced CC members.
Please visit the following URL for the thread ref. my 1883 Hawaiian quarter previously submitted to the CC for opinions.
http://www.coincommunity.com/forum/...1883,quarterThe obverse and reverse pictures shown in the above thread display either a MS-63 or MS-64.
You you may want to consider placing my digital photos side-by-side with your digital photos for comparison.
fyi
