I got this qaurter in my change a while back and noticed lines of discoloration in the material. Is this anything special?
Some collectors will call this a improperly mixed alloy and normally that's probably what I'd say. Then I read this article my a error coin expert so now I'm not so sure. https://www.coinworld.com/news/prec...tripes-on-coins-are-not-fully-understood.html Although that's an old article, here's more info: http://www.error-ref.com/improper-alloy-mix/
Those two links provide very good information. Thank you. So if these are roller lines, what would this then be considered in terms of like mint damage, error, etc?
