It is something I bought in an online estate auction run by a reputable local auction house for $13. Foolish maybe but I kind of just want to know what it is $13 bad. The estate looked to be a not very serious silver guy. It is on it's way right now, so I will get photos of my own tomorrow. Tonight however I cannot wait to see what you guys think. Forgery? $100K? Plastic? 1c? These are the photos from the auction.   Edited by Kaioti23 05/13/2023 9:11 pm

It looks like it was plated at some point.

Genuine, likely plated, details coin with environmental damage, no collector value in this condition.  to the CCF!

What do you suppose they plated it with? I doesn't look like silver. Al maybe? Zinc...but why, lol. I thought it looked kinda zinc-y.

Oh I didn't know that your could do that with mercury. Just read a bit on amalgams, neat stuff. Will that effect the weight negatively or positively? Positively correct?

Yes, there would be a slight weight gain. But if the coin was light before the plating, it could weigh normal after the plating.

Almost certainly plated; possibly zinc, possibly nickel - I suspect the latter because zinc would probably have turned black by now, plus zinc doesn't turn green, while nickel does. It almost certainly won't be mercury, because mercury slowly evaporates over time, and the silvery colour of a mercury-washed copper coin fades back to copper again after a few decades.
As for "why", that's impossible to know unless you were there watching the plating happen. Maybe someone was trying to make a penny look like a dime (which is, of course, illegal). Maybe someone was just fooling around with chemicals. I personally own a "plated" Australian 2 cent piece, that looks silvery; it's zinc plated, and I only know this because my dad (a chemistry lecturer at university) made it as part of a chemistry demonstration.

Plating is the only logical answer, and the weight confirms it. Just a junk coin, sorry.

Coins rubbed with mercury will have a bright shiny mirror-like finish. How do I know? Friend's dad showed us how to make our steel LWCs look like new again back in the early '70s.

We can say plated, but in fact it is a very easy to achieve in a solute boiling 2 min. and the cooper coin will achieve a silver color. The bigger damage it is this reaction it is not reversible.
