Some of this stuff is hard to do at home. When we did the "Silver And Gold Penny" lab, it required hot sodium hydroxide (!) which I wouldn't want to deal with outside a laboratory.
One of the ways to silver plate is to dissolve silver cyanide in a solution of sodium cyanide and then plate from a silver electrode. Cyanide is VERY toxic and can be absorbed through the skin, or if the solution gets acidic, you have hydrogen cyanide, gas chamber gas...stay away.
What can I say. I saw them and had them. Probably put them in the register. Was not a coin collector back then. Just thought they were weird. By the way you should take something for that cough, sounds nasty. Thanks for the greeting on my very first post. I collect coins but consider myself to be a novice. I have fun with it. Just got a 1913 Buffalo nickle unc. To me to have something that old is cool.
Be assured you didn't have 8 1974 aluminum cents. You didn't even have 1. Whatever you think you saw, whatever you think you had, it was something else.
People on here like to be humorous, but 1) usually don't joke about coins and 2) if you do, at least use a smiley face Oh yeah, welcome to CT.
I also have a 1984 D Lincoln cent that is silver. Is it possible that it may have been struck on a 20 (cent) Panama silver coin planchette?

The market for those has declined over the years. It's a shame because I have so many I spray painted like that and gold ones too. Did you ever find a gold one?
