Spooning I have heard of but heard it called Prison coins. where a coin is tapped by a spoon or other metal item slowly on the edge to make a ring usually by flaring out the edge of the coin. Guy at a flea mkt gave it to me, said he did that while sitting in jail ..lol
The planchet is the metal disc from which a coin is made. Pennies 1983 and later are made almost entirely of zinc, with a light copper plating. Before 1982, the planchets were copper. And in 1982 you have some copper, and some zinc pennies, as this was the transition year. On 1982 dated pennies, if you want to check to see whether you have copper or the zinc variety, you would need to weigh them. Copper pennies weigh 3.11g and zinc 2.5g. Also the copper ones when dropped make a sort of a ring tone, versus the dull sound of the zinc. (Similar to silver coins that when dropped on a counter or other hard surface, you hear sort of a bell tone, versus the dull thud of copper-nickel coinage).
You call it "smooshed", and I call it "muddled". If you were an old bartender, like me, you would know how to make an Old Fashioned the correct way. My point was, Mr. P. that I think two things happened at different times. First, a circular grinder was used to disfigure the coin. Then, it got caught in a dryer to enlarge the rim and "muddle" the coin. Chris
1982 was a transition year for the metal composition of the Lincoln cent. It changed from primarily copper to primarily zinc. Unfortunately, the zinc coins do not hold up well in circulation, and that is why I call them Crappy Zincolns". Chris
When found metal detecting it is even worse. Often they will have have chunks of metal missing, as though something took a bite out of them
Prisons and jails haven't used metal utensils for a long time because they can be used to make "shanks". He was probably giving you a story to pass along. Chris
Oh! My primary MOS was 93 Charlie, but I can't talk about it. My dad was a combat medic.....79th Div, 314th Inf, WWII. Please tell your daughter that I said, "Thank you for your service to our country!" Chris
