@dn1, first welcome to CCF. Second, I agree with @jimmy that your quarter is damaged. To me, it looks like this coin was compressed between a hard, textured surfaces. Is there a similar phenomenon on the other side too?

Reminds me of being pressed with a file. One direction, then on some areas at 90 degree differences. The mark on the rim show it even after the damage that happened earlier to the coin. Also the file was solid as it on hits the tops of the devices. (face area) PSD. Spender.
