I found this penny that is missing the last number in the year. Also it appears to be miscut. Did the magnet test just to be on the safe side. The magnet did not attract the penny. Can someone plz tell me if I'm on to something here?
I'm not an expert, but I believe that is a clipped error from the mint. I've found clipped dimes via roll hunting, including silver ones, and they all exhibit the Blakesley effect on the rim at both sides of the clip. Notice the weak strike near the clip, in 'Pluribus' and most certainly the missing numeral in the date. Check eBay for values in completed auctions.
The Blakesley Effect is exhibited as weakness of rims or details directly opposite of a Clip. I don't see any Blakesley Effect on this coin and even though it is highly worn, there should be some evidence. I could be wrong but I believe as some others that the Error was Man Made manipulation.
Called a clipped planchet error caused by the U.S mint. The year is a common date but the planchet error is significant. Honestly Ebay is a great tool, using sold listings, to determine value
