What MS67 means
An 1888-O Morgan dollar in Mint State (MS-67) is as good as the issue is known to come: no wear, lustre that is complete and undisturbed, and marks so small that finding them is the work rather than counting them. On a common date this is usually the only grade worth a large sum, because a coin anybody can buy for pennies in every other grade is one almost nobody kept this well.
A slab, a dealer’s list or a price guide may write this grade MS-67. They are the same grade and the same 1888-O Morgan dollar.
