Re: Is rust on an otherwise BU coin a bad thing? An Update!!
Yes. But we need a picture. There's a big difference between actual "rust" and rust-colored toning -
Is rust on an otherwise BU coin a bad thing? An Update!!
Picked up a stunner uncirculated Mexican peso from 1908 but there appears to be some orange rust streaks present, almost look like crayon in a few crevices. Will the coin grade problem free or do I have to remove the rusty toning which is minimal? -

It doesn't look like rust to me. Try acetone. -

If I’m not mistaken rust is ED. -

It’s orange though so I’m not sure that would come from tape. Bought the coin in a flip but makes me think of the color of a rusted staple -

If it is rust - iron oxide - oxalic acid should take care of it. What will happen to the rest of the coin is a toss-up. In the photo it already looks dull from dipping in everything from corn liquor to mayonnaise. -

Nice job, very well done. Congrats on getting an MS64 grade on it. It is a sharp looking piece. Donato -

YES. Anything detracting on a BU coin hurts the grade and eye appeal. -
Re: Is rust on an otherwise BU coin a bad thing? An Update!!
No, this is incorrect. Solvent effects cover solubility (including of intermediates) and are always present. A substance that is harder to dissolve will cause a reaction to proceed more slowly. A reaction proceeding under nominal conditions quickly does not mean solvent effects are not present. Remember we are talking… -
Re: Is rust on an otherwise BU coin a bad thing? An Update!!
Solvent effects are always present. If you have an impermeable, highly non-polar substance, dip will do nothing. Acetone or xylene might (depends). Most commercial dip has surfactants, so it can get at slightly non-polar stuff, but it won't touch real gunk.
