Anyone ever see this before? I recently purchased a 1976 silver quarter. part of the edge is fairly sharp. I got this as to use as a pocket piece to wear down to match other quarters in a set so I might try to wear this down first to make it wear evenly. in the last pic you can see where the rim should be on the edge

Finned rim and not that unusual. I imagine the extra pressure on certain strikes and/or slight variations in planchet thickness contribute to it.

Sharpened for use as a prison shank.

As BH1964 said that is known as a finned rim and is caused by metal squeezing up between the neck of the die and the collar. This can happen from excessive pressure or sometimes from a misaligned die. (die is misaligned in one direction resulting in extra space between the neck of the die and the collar in the other direction allowing the fin to form.)

Slight finned rims not that unusual, especially with top grade milled edge silver before 1950.
