Given the posted pics, I'm thinking rather harsh post-strike damage. Imagine the coin being caught under a heavy wooden pallet at a warehouse store, and being slid around on the 'smooth' concrete floor. I've seen this happen at a Costco--a forklift was moving/shoving wooden pallets around with merch on them . A heavily worn quarter popped out as the move was underway. The coin had been heavily abraded on the concrete.
