What Kind Of Quarter Do I Have. (1999-P)

Thank you everybody for the reply's and the answers. I'm going to keep it and like you said John clean it off with some acetone and seal it up. I understand the difference between the two. I work in an automotive supplier plant as an electromechanical maintenance man and we use steel stamping and sometimes slug or scrap gets stuck in the die or on punches and deforms. Would either cup it out or deform the shape of the part as in a capped coin. Or in the case of a grease one like mine. Would not allow the part to form right in the die.

Note the rim on the capped die coins:

Note the rim? It makes it look like a saucer. Because the cap is on the die, the normal rim isn't allowed to form on these coins? What die a die cap look like?
