I know this isn't chemistry experiment forum, but you guys seem to know what you are talking about: Speedy - I think the situation OldDan is describing is a deliberate striking by a mint employee - not a mistake. Many plated coins have been produced by home science experiment kits, once very popular at toy stores. Share This Page Tweet. They are out there by the millions with many having been sold on shopping networks.
Speedy - I think the situation OldDan is describing is a deliberate striking by a mint employee - not a mistake. But you are correct as well - even a deliberate act would not produce the coin in this thread. About the only thing I can think of that makes any sense is struck on a foriegn planchet as already suggested. Elemental Mercury metal sticks to copper very well and lasts a long time.
Be careful, it also sticks tenaciously to gold. Captainkirk , Jun 13, Looks like a plated cent The only way to tell would be to weigh it or do a specific gravity test. I used to plate coins as a kid with one of these chemistry sets.
It should weigh 3. I also agree it could be plated or It could be struck on a Phillipens planchet. I was going to say that penny looks like it was dipped a bunch of times.

On our food scale, it weighed the same as a regular penny, 3 grams. Our scale doesn't do lower than 1 gram increments, so it could be just over or just under 3 grams. I took a picture next to a regular penny, I hope this turns out ok. Glob , Nov 17, In post 9, Desertgem explains about the science experiments that produces these silver and gold pennies. I've been giving away any I find.
I've come across a few over the last year but most are in pretty rough shape. I will dig through my stock, but it really looks like a plated coin. Back in the day when high schools still had auto and metal shops, guys would play with coins. They acid dipped cents to make them the size of a dime for use in vending machines, chrome plated them for the heck of it and so on.
By that, I am guessing your coin has a post mint damage. We would even solder quarters to nails and drive them into the expansion joints in sidewalks with a plastic mallet to watch people try and pick the coin up. It must be a coincidence that the OP's penny and mine are the same year.
The chrome plated theory holds a lot of water. Unfortunately, my dad has been dead over 20 years, so I can't ask him, but he graduated High School in , and the date of the coin is , so it very well could have been a High School experiment.
He was into cars, so an auto shop class at school seems likely. I'll have to try one of the experiments mentioned earlier. Would you suggest an older copper penny, or a newer zinc penny for that?
