By the way, this is a " LMC", not a " LWC".  |

The side result of die polishing. That portion of 1 wasn't polished off, the die was polished with abrasive diamond polish, some residue " filled" that crevasse 1 in that corner inside. Otherwise known as " Struck Through Grease" or greasers. BTW, that diamond polish gets really hard and compacted with multiple "smashings" Need to label this variety "the toothpick"!.  |

It's kinda like green casting sand. Seems impossible to hold its shape, but then pound, pound! ... and you have a rock hard surface.

I am wondering if diamond polish is reserved more for proof dies?
I am thiinking that aluminum oxide cloth was used on business strikes and that one way to tell the difference is that the aluminum oxide leaves die polishing lines, whereas diamond polish does not.
Can anyone clarify?

I feel this is a Struck Through Grease issue. Note how the overall size if mostly there. When the die has received an isolated area of die polishing it is in the clash area and it removes the wider portion of the devices, leaving a thinned digit.  Note how this digit was reduced? (the deepest portion of the dies devices are the most tapered, the widest of the upper part of the devices) Unlike the OP's coin. |

I found a 1968 D with a similar defect a couple of years ago. Here is the link if interested That is especially interesting! I have not seen this before on the 1 or any other number or letter. Most curious. It makes me wonder if it is coincidental or not! Thanks, Lewis! |

I have also found several of these in an OBW roll a few years back.. all affecting the "1" in a crescent moon shape at the bottom left side .. I'm fairly certain it was a a roll of 1958 D cents.. I would have to go digging for a day or two to find them..

Thanks for those 2 additional examples.
In these examples, it is always the lower left portion of the 1 which is filled. It is looking less coincidental. I wonder what minting process contributes to that?

It had isolated heavy die polishing to remove a die clash.
