The upper left cent was dipped in either sulphuric acid or hydrochloric acid, in science class back in the 70s. The elongated Canadian is either a train track cent or machine rolled from the 70s, I used to do both, can't remember!
You had me excited at the beginning.I thought you found a bunch of old coins in a old bottle possibly in a creek lol.The Canadian cent is pretty interesting,looks like a train pancake.
I had an old milk jug I found in the 70s as a kid and filled it up with anything interesting I found back then! Mostly wheat cents, and a few foreign. Decided to search through it again!
Yes, we used to do a bunch of "dangerous" stuff back then! I remember handling liquid mercury and my friends and I would see who could gather up the most!
In sixth grade, there were two science teachers. I got the one who started the year by making us write reports on ancient civilizations. The other one was the one who let students roll mercury back and forth in their hands until it had all fallen into the cracks in the hardwood floors. (They tore down that building a year or two later. I don't remember anything about any hazmat cleanup being involved.)
Let's not forget the "mineral wool" used for attic insulation! I've torn out a bunch of that stuff, never really knew what it was back then! Oh yeah, and banging brake drums on concrete to get the asbestos brake dust out, then hitting it with some compressed air!
We had great toys back then. I had the Gilbert Science Labs that contained only the 'healthy' U-238 and mercury that we played with. Now what was it I had for dinner tonight? I can't seem to remember.
I'm not very good at spotting varieties, I probably put that one in the jar back in the 70s because it had an S mintmark.
I must add, when we figured out what capacitors were, my friends and I used to bring them to school and "toss" them to each other as a prank! They weren't big capacitors like for an AC unit, because no one had AC back then. But it would definitely get the attention of the pranked!
I missed the Gilbert nuke set, but the Gilbert/Chemcraft warehouse was local to us. I remember Mom taking me out there to place an order from their catalog in person and pick it up. Better yet, I remember them having a warehouse sale, where I was able to pick up some things from their older catalog -- including some more toxic stuff like barium chloride. Still nothing suitable for getting in big trouble, though; that stuff, I had to order through my school.
