Why would you scrape, running that one-in-several-million chance of damaging a valuable find, when you could just use a magnet?
Well, I won't be setting up that regularly scheduled delivery for you to authenticate all of my copper 1943 cents, then.
But why go through the trouble of copper plating a weak digit steel cent? You would think they would pick a better specimen if they were trying to assure people it was genuine.
Well, you'd better check with the USPS right away because I haven't received any deliveries from you. Chris
I seem to vaguely remember (from the early 60's) that metal items could be copper plated by putting them in a copper sulfate solution (CuSO4). Is that correct?
Yeah, as long as it's a more active metal than copper. Steel is, and zinc most definitely is. The results aren't very good, though; instead of making a smooth, dense, compact layer, it tends to be loose and furry. Similarly, if you dip copper in silver nitrate solution, the copper "displaces" silver, meaning silver replaces some of the copper. Hang a copper wire in the solution, and it'll turn into a tiny silver Christmas tree, with silver branches growing out from the wire.

Thanks for the post. Someday perhaps Whitman will include a hole for a 1943 copper plated steel cent.
you can see where they held the coin during the electroplating process. 1:30 and 6:30 on the reverse.
Advertisement out of a coin magazine in the 1960s. You provided the cent and paid for the service, so any responsibility was on you . One reason there are so many around.
