Coin and Paper Money Collecting/1998 D idk what to call it penny


at a glance, it looked the same thickness as any other penny. But at a closer look of the outer rim, I guess one side is the same thickness but if you follow it around it gets very slightly smaller just above the mm date and the rim has a very small flat spot right there with a / in the metal. I'm not sure that it means anything though. I will have to wait until later before I will have a chance to properly check the weight. So, is it safe to say that you don't know what to classify this as either? That's ok. thank you anyway.


My understanding of the minting process leads me to believe that it is most likely an altered coin (which is something a person asking a question does not want to hear). I know of no process and/or condition that would allow a struck Lincoln cent to receive a second strike of two reverses. The obverse and reverse dies are of different diameters. This prevents two obverse or two reverse dies from being placed into the chamber to strike coin blanks with.

Without the weight, thickness and metal composition, it  is difficult to identify what you have. It's not a strike from a previously struck coin, as it would be reversed (brockaged) and struck inwards.

The coin should be examined by an expert in the field, with the equipment to pinpoint what you have. I do not have this. You may want to pose the same question to a Yahoo coin group. See:

If you decide to send your coin to an expert/dealer in the field. let me know. You will have to pay for postage and insurance both ways.

See: for examples of "fake" errors.

Hope this helps.
