These are the brassy cents. They are found mostly on 97, 97D, and 98 Lincoln cents. Too much zinc was added to the copper plating giving them a brassy look. Instead of a copper red.
I guess Larry got himself a ray gun! I wonder -- is the copper shell on a Zincoln really thick enough to measure it as pure copper without a zinc signal bleeding through? If so, does heating the coin enough to let zinc diffuse into the copper leave a product with the same signal?
What was the device used to measure the elements? And where and under what supervised/controlled circumstances was the analysis conducted?
This is the same conversation we got into the last thread about them. Some say that this can be done with heat. I like Jeff's thought, how do you not read the zinc planchet. Do you measure the content of a plating blister or where you think the plating is the thickest. I don't know?
I'm curious what the weight of that cent was. Anyways, you can easily change the color of the copper surface, remove zinc, etc.
I know this is one of those "yellow jackets" where zinc contaminated the solution during the copper plating process causing these to look brassy... My issue is with the percentages on the label. I bought this knowing it was an obnoxious label for my collection.
not sure if this will help but i got a pair of x ray glasses from back of boys life magazine. so far i can only see thru clothing.
I was always curious about these different "colors" as I would in the past change the color of cents just for fun. here's one example:
when ever my step-dad and i would go to eat he would make all his change completely disapear between the restaurant door and the car door.he didnt believe in coinage. lol
