biokemist6 Bedrock of the Community United States 12437 Posts	Posted 05/04/2011 10:57 am What I see here is two pictures with blinding glare and a third picture with a pinkish orange tint, none of which are sufficient to authenticate an unplated planchet error. A picture should be taken with a properly set white balance and a normal Zincoln should be next to the coin in question. One was posted yesterday, look at that post to see what a difference good pics can make for authentication. Report this Post to the Staff

jbuck Moderator United States 187862 Posts	Posted 05/06/2011 10:40 am It could be that the copper wash used to plate this cent was contaminated with a significant amount of zinc, making it (and other that were plated at the same time) appear much lighter than normal.

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 05/06/2011 11:00 am I am almost certain it is not an unplated planchet, the color is just not right. As you can see from the 1943, zinc has a distinct silvery blue hue but your 2007 has a pinkish-orange color. Jbuck mentions one possibility and I have seen many Lincolns with a plating lighter in color than normal. Another possibility is that your coin has been heated which can also impart a lighter silvery color to a normal Zincoln. What you see as "rust" would be cuprous oxide which will form as a spotty reddish compound when copper is heated. Report this Post to the Staff
