@pris, sorry but no RPMs in 1992. Rather this looks like a zinc blister to me that is somewhat shaped like a letter D. These occur quite commonly near the mintmark, perhaps because the copper plating is stretched extra thin in this region of the coin.

Split plating is the cause that started the alteration on your coin. It is not a RPM. If it had been a DDO, then it could have the hub doubling present on the date/mintmark area. (RPMs stopped after 1990) But it is not even that. Just a split on the plating, exposing the zinc layer that is now rotting. Just a face value coin now.

Agree with all above. The heartbreak of split plating, leading to the zinc rot pox.

Sorry to pile on but it's a zinc blister.
I don't think anyone mentioned above, but the mint stopped putting the MM on by hand in 1989 (I think). No RPMs (or OMMs) after that year.
Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow.

Split plating started on the zinc cents in 1982. As long as the split plating happens, it will always be an issue. Never a plus for the coin. Eventually they will all rot away.  If anything acidic comes in contact, the process will speed up. Never a good thing for the coin victim.

because cents are near worthless and attention is instead given to societal problems that are bigger than zinc rot
