I recall that one of the high class hotels in Greenville, SC used to coat their change in mercury back in the late 40s and early 50s. Everyone who got change carried that stuff around in their pockets until it was all spent. Wow, what we didn't know back then.\

As far as mercury goes, I doubt it's quite as bad for U as the government
says it is........but I've been more and more careful with anything known
to contain mercury the last 20-30 years. Beginning over 50 years ago,
whenever I went to the dentist, he'd give me a few drops of the stuff to play
with. I'd run it thru my fingers, coat pennies with it, and figure out all
kinds of neat electrical projects to use it in (and I have also managed to
save most of it over the past 50+ years.........I probably have a pound or
three of it in a bottle in the basement still). We'd play with it in
school, after school, and nobody ever thought anything about it. Even a
couple of my old toy chemistry sets had a couple of mercury experiments.
Whenever I got a skinned knee, it would be treated with mercurichrome and a
bandage. I have quite a few teeth with mercury and silver fillings. My
doctor STILL has an old mercury column blood pressure measuring system in
daily use in his office........but of course if someone brought any of this
stuff out in public these days he'd probably be severely reprimanded. By
many accounts, all this "exposure" should have made me SK years ago, but I'm
still here. All my mercury switches have been moved to a "safer"
location. Ditto for my not-in-use 866A tubes. I still have a few BAs around
here that use these old rectifiers, but I treat them with more respect than I
once did. If it's something I use more than once or twice a year, I
replace them with 3B28s.
