Removal Of Plating On Nickels, Steel Cents Etc.

Thanks Metalman, but since silver is higher these days, I'll probably just make a couple circ war nick sets out of them and call it what it is or if I can get silver scrap out of them, that's probably all they are worth now anyways.
I just thought maybe someone knew what kind of metal is used in the plating. It is very shiny and I don't know how it is done. If I knew the metal, maybe a certain solvent could be used that just affects the plating and the metal underneath would be safe. To me personally, this is an ugly thing to do to coins.

As to the plating on the 1943 Steel Cents it may well be Chome. Some may be Zinc or even Tin. I like those Steel Cents and have well over 30 or 40 rolls of them. One dealer I know usually has a fair amount of the plated ones and I started collecting them as a novelty. They only cost about $0.10 each so no big thing. I've tried several methods of removal with the basic chemicals such as weak H2SO4, HCl, etc and not much luck. Any stronger solutions would damage the actual coins. It is odd that someone would bother to plate a penny though. Even if sold as new they wouldn't get more than a dollar for each one and I'm sure the plating process would take more than that. Of course if you worked in a plating company the necessary materials are already there.
I've seen some coins that appear to be Silver Plated and would assume that was done for jewlery purposes.
In order to tone down the excessive shinnyness of some of them I've also tried to just let them sit on a kitchen window sill. After almost 1 year, they still appeared the same.
