I have a 1912 Liberty Nickle (pictures coming), that has a blob of something on the reverse, yep, right where the mint mark would be positioned. I have heard of a few substance removers from previous threads (nick o date, acetone, white vinegar, etc...). Should I even bother? I am aware of the 1912-S possibility, but would using these substance removers diminish the value? Especially if it does wind up being the San Francisco version.

I would use a q-tip dipped in acetone and dab the spot.Don't rub it and see if it loosens it up but first I wou ld try just soaking it in soapy water if you haven't tried yet.Acetone evaporates very quickly and will not harm the coin.

On the other hand, vinegar would be quite damaging and should not be used for this purpose.

Nic-a-Date and vinegar are not substance removers and they will damage a coin. Their single solitary purpose is the restoration of a date on a dateless nickel coin by etching the metal. This is a damaging process but a even dated damaged coin is worth more than a dateless coin.

Acetone and xylene are organic solvents that are great for removing surface contaminants and will not interact with the coinage metal. Since they are solvents, they will only removed things of an organic nature(carbon-based) but will not touch staining, toning, carbon or milk spots.
