finger oil?

Hello, 

I put a gold coin on my finger earlier to tap it and there is a very slight colour change from it now hardly visible really. I had not long ago moisturised my hands. 

Will this damage the coin over time (no finger print marks) & can it be removed? 

I have seen you can use a rubber, but that was on silver. 

Thanks.

GOLD is inert

so the stuff you may have "inadvertently" put on it will make its "OWN" oxidation -

wont affect the Gold! but to remove would require a "Specialist" cleaning!

IMHO 😉

It depends what the coin is; bullion or numismatic, bu or proof etc.

Bullion, but it was mint, so its a bit annoying.

I thought as much. In that case i will just leave it as its barely noticeable really. 
I mainly wanted to see if it would affect the metal over time. Thanks. :)

It would be worth giving it a dip in acetone or other organic solvent to remove the oil/grease. It may remove the stain you already have too.

Do any of you experienced coin cleaners know if acetone will remove old fingerprints from coins? 

It may well do. Sometimes it does, or else it needs more of a non-polar solvent, petroleum based maybe.
