First of all, Absolutely Beautiful Coin!! Secondly, I personally would leave it unless your trying to re-grade it maybe? I think it does look like a higher grade though.
Leave it as is....the next TPG could or may body bag it....its rignt where it belongs.....as you could roll the dice...and it could come up craps you loose!
I doubt I'd spend the money to have it re-graded, and it seems the others that have answered think about the same, so I'd leave it as is. Nice coin that I'd be proud to have as is.
"Sure, why not? but crack it out and then what?" It's yours. You have the right to take out your fire extinguisher from behind the glass and play with it if you like! If you want to crack it out and skip it across the lake, or shim a wobbly table with it you have my blessing.
I see two marks on the face that could lower the grade if you were unlucky. The “Cameo” designation can also be fickle. I have seen pieces that definitely had a Cameo not get it.
I did very well on guess the grade. I was the first to say proof. I was high on 66, but given that it is an 1892, I thought I might get some grading leniency.
Don’t crack it out unless you’re willing to take the risk of a lower grade on resubmission or eventual sale. From the photos, I’m not sure it would warrant a + or a full grade jump or maybe a DCAM qualifier, but it might. Great looking coin! The risk-free (except for grading cost) way to see if it will go up in grade is send it to PCGS for a regrade (not reconsideration). They will crack it out at their risk and regrade it. If it grades lower, they will pay you. Pay the extra $5 for gold shield, and you’ll get nice photos too. Cal
