Don't let anybody persuade you to "slab it". There is no reason for you to get it graded or slabbed by a third party grader. You have a known documented error. It would be a waste of money IMO.
To show it off. Found a metropolitan subway token friday in a penny roll. Thinks it from Boston looks really old.
Agreed. The unfortunate fact that so many are under the impression that slabbing is necessary only hurts this hobby while enriching the TPGs. It's not that it's a bad thing, of course, but only that it's not the necessity some seem to think, especially for coins where there's no upside in doing so.
