Pete2226 Pillar of the Community United States 3331 Posts	Posted 03/27/2018 2:37 pm The cent on top is the one in question. The bottom cent is for comparison with my lighting. The cent in question weighs 3.10 g. The closest Foreign Planchet is a 1953 Cuban centavo struck at the Philadelphia Mint. There are a few brass planchets used after 1957, so I think it is not a foreign planchet. I am zeroing in on an Improper Alloy Mix per this reference: Quote: Improper Alloy Mix Definition: The term "improper alloy mix" can apply to two related errors. The constituent metals of a solid-alloy coin can be well-mixed but in the wrong proportions. In the case of a copper-alloy cent with too much tin or zinc, this will result in a brassy color. http://www.error-ref.com/improper-alloy-mix/ Any other thoughts about this?

Pete2226 Pillar of the Community United States 3331 Posts	Posted 03/27/2018 3:12 pm Thanks for the paint idea. Looks like it may be - or something similar. I was able to flake a little off at around the 7k area on the reverse! Report this Post to the Staff
