kurdlezuit Pillar of the Community United States 1034 Posts	Posted 08/11/2023 08:52 am If your talking about the mint mark? It looks like it's probably zinc rot? Hard to tell, the pictures are a little fuzzy. Report this Post to the Staff
kurdlezuit Pillar of the Community United States 1034 Posts	Posted 08/11/2023 09:17 am Here are the 3 main sources we use for attribution sources. It's always good to check all 3 sites for the variety you are looking for. If your looking at the mint mark, RPM. All other devices on the front (Obverse) of the coin ( DDO). Back (Reverse)of the coin ( DDR). These are some of the (varieties) we look for. https://www.coppercoins.com/lincoln/date.php https://doubleddie.com/1801.html http://varietyvista.com/index.htm Errors are a different category, depending on what your looking at on the coin. If it's not a double die or An RPM, OMM. It might be an error. (Too many to list). I will say picture Quality is key for everyone to be able to help you out. Report this Post to the Staff
Petespockets55 Pillar of the Community United States 5785 Posts	Posted 08/11/2023 09:28 am I agree the area at the MM is "zinc rot". This is from a break in the copper surface which allows the underlying zinc core to oxidize. Zinc is considered a sacrificial metal. It will oxidize and "dissolve" before other metals. That is why it is used as anodes on boat motors and hot water heaters. [BTW- Real doubling on the MM would be referred to as an PRM (Re-Punched Mintmark)] Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow.
