I have the opportunity to buy a large lot of Morgan/Peace dollars in old Accugrade photocert holders (see pic below).

I have purchased ASA-Accugrade holdered coins in the past but not this type of holder.  These pieces (65 total) will be sent to me on approval.

Has anyone seen this type of holder before?  Any knowledge on the grading codes?  I'm told they're all graded MS64.

Thanks for any help you can provide!

No real added value in those slabs. Just look them over and if allowed pick out the beat and buy at grey sheet prices.

Thanks Stephanie!
