So, now you know the easy way to get yours coins to change color.

Easy, sure, but if your grandfather wrapped them up when they were new back in 1964, then it's not exactly rapid. 40 years is a bit too long for most AT doctors to wait.

If some kind of galvanic reaction has taken place, you'd expect to see some damage on the foil. Did the foil still look intact, or was it starting to turn white and crumbly?
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

It was a little yellow on the inside, but not as much as the coins. I doubt they've been in the foil since 1964, but probably for quite a while nonetheless. This was kind of started as a joke anyway. Kind of hard to wrap your coins in foil w/o scratching them up

Use soft Aluminum? Use scratchless foil? Wrap, don't rub? Coat each coin with liquid plastic first? Use Aluminum coins only?

Hey, good idea. I've got a 1949 French 5 Franc made of aluminum! Of course, that would negate the difference in metal required to get the reaction

I thought I'd tone some bulk silver someday by placing it in a sulphur vent near a volcano (as I'm a bit of a geology buff)
Then I'd give away a bunch of "volcano toned" silver.


We went on vacation at Mammoth Lakes in the California Sierra Nevada. There is a popular hot springs bathing area and we all went for a hot, sulfur-smelling swim. Afterwards my sister discovered that her sterling silver jewelry had turned a bright purple color.

There's another geology-theme AT option for you, Kurt!
