The other thread is here! 1. Does this error increase or decrease my value of coin? 2. Is same error on same type of penny common? 3. Should I keep this in my main collection? Your thoughts?
After looking at the other thread, the error is rather pronounced. Something this pronounced is not very common, but due to the damage on the obverse side, I'll say that the premium is almost nothing. Frankly, I think it's really cool and that you should keep it if you like it. I would keep it if I found it
