I was picking the copper cents out of a box of pennies yesterday and came across this 1983 cent. It has an area on Lincoln's chest and an area on the exact opposite location, right over "E Pluribus Unum" that appears to be either worn down or flattened some other way. I don't think it has been worn down because the areas aren't perfectly smooth, they have some texture to them. There is a grain pattern on the whole coin and the horizontal lines of the grain pattern in the areas in question are parallel with the lines throughout the rest of the coin. For some reason I think this may be an error, but I have no idea so here are a few picks. What are all of your opinions?
Struck through grease. If you're doing roll searching, you'll find a lot of these. They're very common in different degrees.
It can but not always and sometimes it's just one of the devices that is affected and other times it's more. The "grease" can be become compacted and include other debris and become very hard. It can clog the devices, which prevents them from being struck into a planchet. Sometimes, the clog in the device falls out and is struck into a coin. The pic below is to illustrate just how hard the grease can become: This is a Canadian cent that has a "dropped letter" :
