So here's the 1990 offstrike and i also added a 2001 ghost penny. THe ghost date is not seen here but with roatation you can see 2001 and liberty on the coin. 1990 offset obv reverse 1990 ghost 2001 obv ghost 2001 rev The reason i was unable to get the grossing microscope to work is that i was attempting to photo a 1764 Cathrine I, and its just too big in size to get in its entirety. So let me know what you think of these peenies: good, bad, or indiffrent Thanks N
Narem- The 1990 penny has been struck off center about 30%, which brings a premium of about $4. Your "ghost penny" error is a die adjustment strike, which happens when there isn't enough pressure on the strike. The middle of the coin is usually the only part of the coin you can see, if the error is significant, with the outside unvisible. This type of error can bring as much as a $40 premium if the error is significant. Great coins.
On the "ghost" cent, check the rim and edge. If the design rim is absent, and if the rim/edge junction is beveled, then it's a weak strike. In other words, the rim/edge junction should be indistinguishable from that of an unstruck planchet. If, however, the design rim is well-formed, and the rim/edge junction is sharp, then you've got a coin that was struck through a heavy layer of grease (or similar substance) covering both faces.
