I was recently going through my collection and found this 1968-S penny that appears to only have one side.   Everything that I've read about this type of coin points to it being an alteration. Does anyone have any insight on this? It is about the same width as an ordinary penny which leads me to think it might be an error. Any help would be appreciated! |

Check the weight. A normal 1968S cent weighs 3.1 grams, so we have a starting point.
We also need MUCH MUCH better pictures of both sides of the coin.

Welcome to Coin Community, astreff. Given that it's a physical impossibility for the US Mint to produce a coin like this, one has to assume that some miscreant felt it enjoyable to grind one side off of the coin.

What if two planchets were struck at the same time?

The copper wouldn't be hard enough to prevent some detail from the upper planchet from leaking onto the lower one. Not at 150 tons of striking pressure, multiplied by the press meeting resistance before its' full stroke. Remember, the press strikes with enough force to transfer details from one super-hardened steel die to another, as clashing. |

I thought it was impossible to have a blank side on a coin and a struck side until I saw one in a PCGS slab. You will need to weight it and if it is 3.1 then look to see if it has been altered like a Magicians coin. |

Thanks for the information so far everyone! The mass of the coin is 2.930 grams. Is this worth continuing pursuit? I am in contact with a coin dealer and he could have it graded for me if I would like. What are the signs of alteration?

Need bigger pics of the reverse. The weight alone probably indicates somebody altered the coin.

I hope this turns out to be bigger than the original. Sorry about that everyone!  |

Do you Have a larger image of the Obverse as well? I notice the reverse shows no signs of a raised rim. I want to say it has been tampered with. That's just my opinion. But let's wait to hear what the experts think.  |

Here is the other side of the coin. It seems peculiar that the coloring on both sides is exactly the same. Does this mean anything?  |

You can see the sanding marks on the reverse. PSD |

They don't really look like sanding to me, just everyday scratches. Do people frequently alter coins by sanding them?

The missing half gram should be enough to tell you it is PMD |
