Could have been peanut butter from a mint worker's sandwich, dropped onto a die as it was being adjusted in the striking chamber.

Sorry to everybody, but this it is not Grease. This it is clad problem. Maybe if have grease was after mint strike from counting machine or from roll machine.

The adjustment of the die is made external of the striking chamber. 1 feet away from the chamber are 4 screws which will be employed when the computer fail. Insert the die with holder is done in a chamber trough two rubber arm protection and it is isolate from the exterior environment like for example the sand machines or in UV chamber in laboratory.

Thanks Silviosi. These grease strike throughs are mostly found on Philadelphia quarters. People are calling them field restricted strike throughs and they get bigger than this. Mostly P mm

RW you discuss about 2022 strike. Grease do not exist anymore. It is a glyceridic fluid which will solidify at 350 Deg C. The container is big around 100 litters. Grease was till 2001 the after no more such kind of grease.

Looks like that mark on the temple is a reed contact mark. [ Greaser] includes more than grease, oil, water. It's just easier to say Greaser. Maybe we need to call anything after 2001 glyceridicer.

Thanks Cujohn. Just above and connected to the reed contact there's what looks like a dropped letter error. I could just be seeing what I want to see being there so it may paradolia. I'm sure I spelled that wrong. Gly... It is

RW: say Grease is nothing for a coin. What you have it is a bad planchet, is very clear to me. Probably it is the end of the clad roll, where is the most crazy forms of the material forms. Normally they cut the begin and the end of the rolls to eliminate the defaults but sometimes they cut just is required 2.5 feet which in some cases is not enough. I see shrinks on the surface, I see holes characteristic to the Carbon of the melting. No Grease will do those marks. 2022 production is no characterize by big quality, but this coin is out of the quality is default of the clad planchet.

Thanks Silviosi. I'm ok with defective end of strip planchet. I would be better if it was a dropped letter lol. Identification is the key. Thanks for all the help

Welcome RW. Maybe you look for dropped letter? is OK; but this coin is major planchet default and if the clad roll was like this 1 feet?!!? only max 300 was in the same way. Is cut 25 by line, 300 by feet.

I just can't see this as a planchet flaw. I still see it as a struck through... something. Just the fact that all of this was under the... something points to a strike through.

I'm going to watch this topic, but I'm on the struck through... something team on this one. I have been wrong in the past, may be now and will be in the future.
