I found this penny in loose change. I've never come across a clipped planchet coin and wonder if this is one of them. It had strange punches on the reverse as well. Thanks for your thoughts.
That's all damage that you see all over the coin, including the 'missing' area. Badly damaged, not an error - sorry.......
Your gut speaks wisdom. Remind your gut that if it's a cent post-1982 that you're looking at, post mint damage should be your first guess. Your rate of correctness will soar.
