You can get any coin graded.. If you think you have a Black Beauty, Doubled with full steps then you need to get it Attributed which is a separate service done by Coin Certification companies.. which costs a bit more of course. So.. Coins are graded and Mint Errors and varieties are attributed.
It looks right, but you need to show a photo of the edge. Cost of grading compared to the value, etc. Collectors and dealers know what a genuine black beauty is worth without being graded.
