It does look like a crack but there are two other things I'm thinking: If it was less crescent-shaped and more concentric, I might be inclined to say Die Deterioration or "ridge rim." It looks more like an early stage of die attrition. This is where a mis-aligned die strikes the collar repeatedly and wears down the die and that may start as a crack. I could be wrong about the whole thing, though.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Thank you spruett001 and CoinCents for your input. Looking at your last pic CC, on my coin, the letter 'I' is actually cracked at the top as well as the 'G' and 'O'. It looks like it goes under the 'N' and the 'D'. Thanks again for both of your comments.  |

Bump Again - Maybe Koinpro, coop and/or John1 can offer us an explanation on this one :)

Poke those areas with a toothpick to make sure it's not a plating issue and get back. The other Two Cents with the ridges are due to the upset rim on the planchets wearing the dies out in that area faster than other areas. It's been common ever since they started striking zincs. |

Thank you Koinpro Quote: Two Cents with the ridges are due to the upset rim on the planchets wearing the dies out So if I understand this correctly; this ridge is created in the upset process when the rim is being created and not when the planchet is actually struck? |

Sorry, but no extra added value.
Errers and Varietys.

It does not collapse when pressed Ken. Thanks for your help also. Edited by OldJoeClark

To me it looks like a linear plating bubble that rounds a corner. As Ken mention a toothpick should flatten it. On split plating you usually see a gray area where the zinc is exposed. I don't see that on this coin.  |
