It would be my understanding that the opposing dents in the middle of the clip and opposite rim would be from a foreign object chain strike.
Maybe wrong, but thinking the raised dents or material on reverse occurred after strike. Maybe jammed up a vending machine at some time.
Don't see chain strikes very often. http://www.error-ref.com/chain-strikes/
Chain strikes are sometimes mistaken for straight and curved clips. Several diagnostics serve to distinguish the two errors:
1.A chain strike shows a distinct contact facet while a clip doesn't.
2.Design elements bordering a chain strike show no metal flow. Design elements bordering a clip will show metal flow.
3.A coin with a chain strike will weigh the same as a normal coin. A coin with a clip will be underweight.
Second opinions are always recommended. Rookies thoughts!
Backup data often or good luck with the recovery process..... SME advice!
