Guess The Grade 1968 Silver Quarter

I would say EF details and worth melt value of about 8, maybe 9 bucks

It is a details coin worth bullion. Grade would be irrelevant.
Bullion value today would be $8.70.

Too late guys, I have had it graded because of XRF results but wanted an evaluation of your thoughts. I will say that if it wasn't 80% it would not have been done.

I don't know why you're asking us to guess the grade.
Grade is inconsequential, it's the attribution of this coin that matters.
80% 1968 quarters do exist, this is not the first one posted.

I have had this coin for approximately 2 1/2 years knowing that it was 80% by a sigma metallics coin verifier. Found an XRF machine at a pawnshop and their machine confirmed it. No third party grader in Canada had the capability of verifying and encapsulating it until someone posted their 80% quarter 2 weeks ago graded by SSGC. Somebody then questioned their credibility so I decided to send mine in. I called and mentioned that I had an 80% with a bad scratch that might make it ungradable but would like it encapsulated with the XRF findings and I got it back with a grade assessment. I am not experienced in grading and therefore would like other opinions on this coin before I show it encapsulated and influence any judgement.
