I clicked like because of the post not because I like what you did. The old pencil eraser was a common cleaner back then.
When I first started collecting back in the late 40's there was very little information on coins and collecting. I'm sure I did a lot of the things that are described here.
I actually dropped it and it hit the corner of a metal drawer at work. Being a DC piece, it was always stored in a plastic flip. Z
I put just a pinch of sulfur in the oven to tone one of mine, and everyone in the house was hacking and coughing from the SO2...
Tried to save a coin in a safe place. Wherever it is. I hope it’s still safe. 1912s Mercury from passed hubby. He paid for it a little bit at a time in the 70’s
I did the same thing Rodney @wxcoin they were my dads Lincoln’s. My first lesson on not to clean coins. He did thank me for doing a good job. That’s the kind of dad he was. I never did see that collection again. Wish it is in mama’s Stash. Would love to see what I did 60 years ago
Got a new stove. Baked a cake before I left for a two week vacation and never turned off the stove after I took the cake out.
Sulfur dioxide (SO2) is interesting, you don't as much smell it as you taste it. When it hits the water in your throat, it forms sulfurous acid and makes you cough...then you taste it...yuck
When I was about 8 my grandfather gave me about a dozen dateless Buffaloes. I thought I would try to expose the date with some jewelry cleaner. So, I took them, dipped them in a bowl of said cleaner, took a toothbrush and went to town. Well, turns out submerged hands in jewelry cleaner will blister the skin quite severely. Needless to say, they are still dateless and I still won't collect Buffaloes, for some reason unbeknownst to me.
I would but I worry that my older brother is a CT member and he'd find out that his missing Mercury dime ended up on a train track rail.
I just wanted to add that in 1970, 71 or 72, my brother worked after school at a dry cleaners my dad also worked at. He used to go through the cash register change and exchange things like mercury dimes (that is what he was into then). One day he came back with a newly minted Washington quarter that looked unusual (wrong planchet or something else that made it look smaller, or something like that). He didn't seem interested in keeping it so I asked him if I could have it. He wouldn't let me have it. The next day or so there was a Coin World article about the exact same coin error; I wish I could remember the date and article. Long story short, when I asked him about it after school he said that he lent the quarter to a classmate so he could have enough money to buy a hamburger at the lunch cafeteria at our high school. Needless to say, I felt revenge was in order.
