jfeed Pillar of the Community United States 1259 Posts	Posted 09/30/2023 7:35 pm Looks like a popped zinc bubble on the mint mark. If you're talking about the G in FG, it is the correct one for 1988. The 1989 had the "flare" G. I'm not the expert here and I'm sure someone with more knowledge will respond shortly. Report this Post to the Staff
Spence Moderator United States 34397 Posts	Posted 09/30/2023 7:36 pm Hmm I think that there is a bit of zinc showing next to the mintmark (split plate doubling). It isn't a RPM.

mrwhatisit Pillar of the Community United States 2953 Posts	Posted 09/30/2023 7:41 pm Well Crater, this is a good example of zinc rot, where the thin copper plating is wearing off exposing the zinc core. This zinc rot can get worse over time as the zinc is more reactive than the copper. As to a flared G, might be more of the same issue, others might have more insight on that phenomenon...

Errers and Varietys Bedrock of the Community United States 73770 Posts	Posted 09/30/2023 10:36 pm Agreed, a zinc bubble aka zinc rot. PMD on the mint mark. You also have the normal reverse for '88. https://www.lincolncentresource.com...988RDV6.html Errers and Varietys. Report this Post to the Staff
