Besides gold, what coin is least likely to tone?

My vote goes for the 3c nickel. Strange how I'll see toned Liberty; Buffalo and Jefferson nickels all day long yet the 3c nickel is rarely seen toned?

    Of US coins alone... I guess I haven’t seen any toned (other than dulled) flying eagle or 1859 IHCs.

    Tarnish depends on material and environment.... Ideal conditions will tarnish most coins...Environmental protection at an early stage will prevent tarnish. Different alloys will tarnish at varying rates. Cheers, RickO

    Stainless Steel

    Actually, 3CNs tone a lot. Usually a haze (acetone works great on them), but lots of them toned a cool blue (check out the specimen to the left here) in reaction to sulfur in the paper they were originally shipped in.


    Here's a warning parable for coin collectors...

    @jmlanzaf You do realize Stainless Steel has been used for coins.

    Actually, it sort of seems like our nickel coinage is less likely to tone the older it is. Maybe it's statistical, but I handle thousands of Liberty and Buffalo nickels and it seems like I see more toned Jeffersons than Buffalos, more toned Buffaloes than Liberty, etc.

    I wonder if that observation is true if you look at ONLY true UNC coins. It might just be that the older coins tend to be more circulated resulting in a passivating oxide layer that results in a stable dull gray color rather than an unstable silvery color that then can undergo more colorful oxidation.

    Just thinking out loud...to avoid grading yet one more lab report.

    Yes, although not in the US. Fair number of European examples. It just struck me as funny when the OP started with gold.

    It's funny how LOL has become derisive rather than a sign of good-natured laughter.

    Pat, do aluminum patterns count? If so, that's my answer.

    They're around - both business strike and Proof examples of each.

    I figured there might be. I just haven’t run across any of them.

    Aluminum is an interesting case. It is actually incredibly reactive and oxidizes almost instantly in air. The thin oxide layer is somewhat unique in that it forms an intimate protective coating that prevents further corrosion. So, it corrodes (imperceptibly) , but does not tone. :)

    Their are non-U.S. aluminum coins. The OP didn't specify U.S. So, either way, I think aluminum counts.

    If acetone removes it, it isn't the metal toning.

    That is an interesting "cool blue"

    I believe that mild steel reinforcing in concrete does something similar, creating a passive layer that further protects the steel from the alkalinity of the cement matrix.

    Yes, aluminum was what I was thinking. Nickel was on my list as well.

    As for Zinc, it never gets to tone; it dissolves first. Has any one seen a modern cent, without its copper coating, that was nicely toned?

    I have some zinc coins from WWII that a guy in France gave me many years ago. They're pretty interesting - they're decently large, but weigh next to nothing. Their color is plenty ugly too. If I remember, I'll take a photo tonight.

    Yes, the zinc German coins almost always have horrid surface conditions. Zinc is just too reactive. Any exposure in a humid oxygenated environment for very long just corrodes the heck out of them.

    Of course, although I was thinking of circulating coins in general when I prepared by question.

    Platinum first came to mind. Any of the PGMs should be inert and never tone, under normal circumstances

    Russia minted and circulated coins made of platinum.

    I used to own 1/2 a dozen 19th Russian Platinum 3 roubles and they were toned to a degree.

    There are gold-plated platinum spanish counterfeits that circulated. Do those count? ;)

    They should probably strike coins in magnesium so you could actually watch your money burn

    Or with mercury and they will melt in your hand.

    Nah, mercury is a liquid at room temp. Try Gallium. Melts at 86F/30C. That might be one of the few things worse than copper plated zinc for coinage :D

    Also look up "gallium spoon"

    BTW: a thoroughly useless piece of info that may only interest me. Even though gallium has a very low melting point, gallium nitride melts at over 4500F
