tershaffer Valued Member United States 232 Posts	Posted 01/25/2011 02:50 am hi all Pulled this from a bunch of coins I have had since a kid. It's a 1928 penny with the back as a blank. The front has what looks like paint or something on it. I tried cleaning it with Acetone, but did not work. Any suggestion on how to clean it. Also, any premium on this?

Nobody can really tell you what to do without knowing that piece of very necessary information. 2. Your coin is not an error - the reverse was ground off the coin after it left the mint. It is impossible to strike one side of a coin. Report this Post to the Staff

tershaffer Valued Member United States 232 Posts	Posted 01/25/2011 10:39 pm Sorry, the substance on it looks like silver paint. I did not know anything about the die process, but after reading up on it a bit I now realize that both sides are struck simultaneously. just thought it was odd that there is no rim or grinding marks on the back and it is perfectly smooth.
