does anyone know how to remove oxidation from nickel?
I have old nickel coins that have crud all over them, and I have tried all the conventional methods and most do not work.
now the only things remaining are the harsher acids. thanks

I've cleaned many a nickel bolster my knife collection with a simple solution:
#0000 steel wool.

If tooth paste doesn't work grab some concentrated lemon juice out of the fridge and some aluminum foil. Place the aluminum foil in a tub and dump in the lemon juice. Toss your coins in and forget about them for awhile. This will help remove oxidation without scratching or causing any further damage ot your coins. Works great with pennies too.

Have you tried powdered aluminum cleaner, made for pots and pans? It cleans lots of other metals, including stainless steel and brass, through a mild chemical reaction rather than just scratching the hell out of it to get stuff off.
Of course, if the coin is collectible, don't mess with it, but it's worth a shot if there's some Cameo in the house or if you care enough to spend $1.75 or so.

Caution.
More than casual cleaning can destroy
the numismatic value of 'collector` coins.
