AMB Pillar of the Community United States 801 Posts	Posted 08/15/2014 5:01 pm Here is a 57D/D, but my question is the Red color...I get 2-4 of these in each handful. Is it a different oxidation process? Different % of alloy combination? Does it attract collectability when found say with an error? Just wondering. Report this Post to the Staff

Adam_E Pillar of the Community United States 4846 Posts	Posted 08/15/2014 5:11 pm I believe it's just patina/toning, if you're referring to the colour of the entire coin. Toning can occasionally increase or decrease the value/collectability , but it all really depends on if the collector likes toning or not. I personally love a toned coin, and would pay a little extra. Edited by Adam_E 08/15/2014 5:44 pm Report this Post to the Staff

Groszy Pillar of the Community United States 589 Posts	Posted 08/15/2014 6:02 pm Think I head those were copper stored around tobacco, or at least a little too close to tobacco, which causes the red toning. Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 08/15/2014 6:10 pm The red color is caused by the formation of cuprous oxide. Report this Post to the Staff
AMB Pillar of the Community United States 801 Posts	Posted 08/15/2014 6:33 pm THANKS Biokemist6...this was a perfect question for you (I would assume)!! Just looked up cuprous oxide, aka Red Copper Oxide...regarding the penny it might be the result of where the coin was stored at some great length of time. Also if it was at the end of a roll in let's say the "attic", ...the warm moisture. Anyway, no it's not a red marker. I kinda like these, and they stand out.

themetallurgist Valued Member United States 111 Posts	Posted 08/15/2014 11:16 pm could have been heated up fairly hot. Report this Post to the Staff
AMB Pillar of the Community United States 801 Posts	Posted 08/15/2014 11:27 pm Maybe heated but I have numbers of these from different years 20's-50's and it's a "copper red" like a barn red almost...few at a time though. Report this Post to the Staff
