A friend of mine sent me a pic of a penny he found in circulation and wanted to know my opinion of value. Having no opinion, and thinking this is simply a coin that has a very well worn side, I still said I'd throw it up if he provided a picture:  After looking at it, still of the opinion that it is simply a worn reverse. But I also have next to no experience, and have no idea if one sided blank coins are even possible (couldn't find any examples). On a side note: the friend did say the coin was the same thickness as a normal penny. Thoughts? Opinions? Using this as a personal learning experience as well.  |

Striking a coin on one side is like trying to clap with one hand- it is impossible. The coin did not leave the Mint looking that way, there is no trace of a rim so the reverse was most likely effaced through artificial means.

I have seen a slabbed coin with one side struck from NGC.

Looks like a worn coin to me personally. Most uniface strikes I've seen bulge outward on the blank side, but still have a distinct rim, but that could have been worn down with time, definitely possible though. Here's some info about uniface coins, hope it helps.
"Uniface coins occur when there have been two blank planchets in the press at the same time. The other blank will obstruct the die on either the obverse or reverse side, which will prevent it from having that design on the coin. There are many different variations involving uniface errors. In addition to having a 100% blank obverse or reverse, a coin can be struck off-center, with a blank planchet in the collar which will obstruct one side of the off-center. There are also mated pairs which have a combination of multiple errors which can include a side which is uniface. Finally, there are uniface strikes due to a die cap which adhered to the die, forming itself in the shape of a die and striking blank planchets."

Weigh the coin. That'll tell whether it has PMD |

How about a pick of the other side?

Side has been ground off. Yes you can get a one sided coin if two planchets enter the coining chamber at the same time, but the result is NOT a flat smooth surface.

A uniface strike is not the same thing as striking a coin on only one side, two dies are still involved. A uniface strike will have an upturned rim and there will be some minimal detail/signs of striking transferred through the second planchet as well. The lack of an upturned rim, completely smooth surface, and light vertical striations indicate that the reverse was removed. This coin will also be lighter than normal. Quote:

Then again MadMortician...Some one could have used a sander (see photo) for sanding marks..Weighing the coin can help.  |

I asked the friend to send a pic of the obverse and try and get it weighed, and was told that he put it back into circulation again. CRH keep your eyes open. Edited by MadMortician

The blank face was ground off. Any time a blank face is as flat as a pane of glass, it's certain it was mechanically removed. This coin will be underweight.
