Hey guys, I just got this penny in change today...looks like I found something? There is no mint mark on the obverse but a clear multi struck or RPM "D" on the Reverse just left and north of the Memorial building. There also appears to possibly be an "S" floating nearby that I JUST noticed as I posted these photos. Not sure if the possible "S" is raised or not, Ill check it.      WHAT DO I HAVE HERE? 1) What is it called when the mint mark is on the "wrong" side of the coin? How rare is this? 2) It looks to me like the obverse and reverse were both struck through cloth? It is in the fields on the reverse and on Lincoln's coat and forehead on the obverse. 3) Is it also Struck Through Grease? Or is the black stuff post mint? 4) How rare is this coin? 5) What value would you guess at? THANKS! Big Al  Edited by big al

Your coin has damage on it. The "mintmark" you see is a raised area of zinc rot.

I am going to say its gas bubbles associated with the 80's zincolns.

 Sorry. It does look a lot like a 'D' but it looks to be too tall above the field and there is no way a MM could appear on the wrong side (in 1987) as the MM was not applied in some separate process. Same thing for the 'S'. Besides it doesn't seem possible that a coin made in one location would wander over to another mint to get re-punched. It does look like it was struck through cloth but I believe that pattern is really a whole bunch of tiny gas bubbles. There may have been a patterned flaw to that planchet. I don't know what the black stuff is. But the black stuff on the obverse looks PMD. Those zincolns from the 80's have a lot of stuff show up on them. |

Interesting find ... but just a curiosity that has already been correctly attributed. The 'extra' mint marks you are reporting are in fact gas bubbles in the zinc plating which are common in '80s LMC. Someday we'll get a post of Jesus on a cent.  The coin IMHO is not struck-through anything ... but has some PMD smudge on it. Value is 1 USA cent ... same as stated on the reverse. BTW ... for your information ... Quote:

If you saw it in person it REALLY looks like a "D"...hmmm
If it is a gas bubble will a toothpick dent it?

I would say it is probably zinc rot under the plating. The S is most likely a case of the mind trying to force random data into a recognizable pattern.
Buddy you are wrong about the D mintmark not being applied by a separate process in 1987. The cent didn't switch over to being on the master hub until 1990. But you are correct in reference to the S mintmark. Those went to the master hub for all denominations in 1985.

Gas bubble indeed.
Before suggesting an errant mintmark consider what would be required to create such a thing. The person sinking the mintmark in the die would have to deliberately pull a reverse die, mount it against policy and procedure and hammer an S into it, also they wouldn't have an S or D punch if located at the Philadelphia mint. Often times logic and reason, just good ol' common sense can answer perplexing questions!

I read a lot of these posts and you forensic numismatists are unbelievable! The things you know about die errors, lamination issues and gas bubbles amaze me! Keep it up.

Condor101 thanks for the correct information. I had it in my mind that the MM switch to the master hub was in 1980. Clearly I need a better place to store my information.
