Hi Guys,

Just brought to my attention about this coin, lm have checked on variety plus, but unfortunately don't see image about RPM D/D of this coin as FS 501 and can anyone help me identify about this coin? Or this coin is PMD?

thanks and really appreciate for any inputs about this coin.

Jay

It looks like split planting that is corroding.  When the coin was struck, the metal flow caused the thin copper plating to split, exposing the zinc to the elements.  Over time, the zinc has started to corrode.  It's not an error.

You'll see this on cents, especially from the 80s. It's seen frequently in the date/mm area.  

BTW: the following sites have extensive listings of RPMs.  Your coin won't be there because it isn't an RPM, but they are good sites to bookmark (They are also excellent resources for doubled dies)

Once zinc rot has set in, there's nothing you can do as far as I know.  The coin is doomed.  It's best just to spend them.
