Eww, this one is being eaten alive by some white stuff. Copper corrodes green and only iron-copper mixtures corrode with white. I suspect that the zinc in the coin may started reacting to an acid seeing how both sides show liquid damage.
Here's the stats...
Type/Country: 1 Cent / Canada
Metal: 98% Copper,1.5% Zinc, and 0.5% Tin
Value: $0.02 in EF-40
Do you have a cent
from Canada and want to know its value? Leave a comment/question and I
will do my best to find out the price and history for you.
