Kawi66 New Member United States 2 Posts	Posted 09/16/2014 10:41 am I found this today and cleaned it up a bit to see if it was just stained, and it appears it either be blended or possibly have some type of copper foil (although it didn't come off when scratching it with my fingernail. I was wondering if anyone else might have come across something like this. Report this Post to the Staff

Kawi66 New Member United States 2 Posts	Posted 09/16/2014 4:17 pm I did some more research, and it looks like this in real life. The lighting I was using isn't very good.

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 09/16/2014 4:38 pm Sorry to say but you coin is just corroded, not a mint error. Nickels are actually 75% copper and corrosive conditions can cause the coppery color. Notice that the affected area on your coin is rough and lacks the luster present on the rest of the coin. The border of the affected area is also highly defined, that defined border would be caused by an accumulation of liquid which caused the corrosion. Report this Post to the Staff

unholyroller Pillar of the Community United States 1903 Posts	Posted 09/21/2014 12:21 pm I have long experimented with using electrical processes for removing crud from buried/corroded/damaged metallic items. What scares me most about this thread is that the TPG actually called that coin a mint error! I could pretty easily replicate that coin in a weak electroplating solution. To grade something so easy to fake just makes me worry about how TPGs are actually promoting an environment of forgery. By calling something genuine that is that easy to fake and say it is genuine worries me. Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 09/22/2014 1:23 pm The first coin is most definitely not a mint error but the second coin(2004 Keelboat) was indeed struck on an improperly annealed planchet and it is a genuine error. You may think it would be easy to fake but that is not the case, you would never be able to convincingly replicate the luster present on the coppery areas. Report this Post to the Staff
