I have one also from 1983. As an example from Google. https://sullivannumismatics.com/pro...sitional-struck-copper-cent-planchet-ms-63-rb I'll put pics of mine in a follow up post
Hi Tom You title states Copper Coated Nickel. The link you provided is a Nickel struck on a Cent Planchet which is something totally different. I nickel struck on a Cent planchet would be the same size and weight of a Cent. Sometimes Nickels are affected by the environment. There are what is called Environmental Damaged Clad coins that take the color of Copper when in fact they are not. Edit* - Looking at your pictures.. you have what is considered Environmental Damage.
I believe I have shown you this coin before from my collection - This is a Nickel struck on Cent Planchet
On a very positive note, though; you're clearly looking deeper, willing to search out information, and taking the time to educate yourself, which is something a rather appalling number of people are no longer willing to do. Paddy is, unfortunately, correct in that your coin displays nothing more than damage, but you're on the right track and will do well in this hobby. Kudos, Tom.
Tom, check out these coins I have dug out of the ground metal detecting... with Environmental Damage! They take a dark color.
Thanks for the replies. YouTube makes this sound so easy. But I'm hooked. I have my scale, my metal detector now and a few books.
