    I am not a fan of tarnish on silver coins...and I strongly dislike it on gold. I realize the alloys of silver and copper are subject to allowing this in some cases. I still don't like it. Cheers, RickO

    You must hate this one:

    @Smudge .... Hate is a strong term, and not applicable to the situation. I do not care for the aesthetics of that coin and would not consider it for my collection. Cheers, RickO

    Other alloys do different things. 75% gold 25% nickel is often marketed as “white gold”. Gold is essentially inert but the copper and silver in gold can tone to create a nice patina. Some of what is shown above is staining or “dirtying” of otherwise normal surfaces. I kind of like a bit of color on my gold, but not too much.

    These are “about right”, especially the reverse of the $10:
