Anyone see one of these before on a 1987-D cent??

You might be able to blow it up. its a 2300dpi scan. The mint mark looks repunched to the SE. Any thoughts?

Maybe- hard for me to tell from the scan- but it looks like there's something there. Not just a shadow, I take it?

Tough to tell but the zinc cents can be very decieving because of their
tendency to "bubble" near letters and design features. The thin copper
plating separates and will often look like doubling.

That could be the case. I'll have to look closer at it. What is the best way to get a decent close up of a mint mark? Anyone know??

Not repunched. It's either what cladking says, or possibly some kind of abrasion or deterioration doubling. From the Cherrypickers' Guide, Fourth Edition, Volume 1, page 327:

"...beginning in 1987 the mintmark was added to the master die, and later (1990) added to the original plaster sculpture."

These are very common on zinc cents. What this shows is plating split at the mintmark....not a repunched mintmark.

To add, repunched mintmarks exist on cents through 1989.

coppercoins is indeed correct! I didn't dig far enough for my info. Wexler/Allen's "Lincoln Cent Mint Mark Varieties" lists nine RPM's for 1989, eleven for 1988 and thirteen for 1987. Apparently the quote I gave from the CG was a general type of comment, and the process may have begun then, but was not yet being used "across the board," so to speak. I don't think this example is one of them, however, and I agree with the others that it is most likely a bonding problem.

yeah...what they said....

i call em "strech marks" its where the thin copper plating is stretched and torn around the letters ...commonly on the mint mark .
exposing the zinc underneath.

"I" believe its more common on the mint mark.... because the mint mark is hand punched into the dies...and many times this punching is
deeper than usual....meaning that the flow of metal has to "fill in" the mint mark area at the moment the coin is struck, and thus the copper tears as a result of the metal trying to flow in too many directions at once.

copper coins...how close am i? i could be wrong ...or some what right.
