coca-cola has an pH of 2.27 >> the most acidic among the softdrinks that we experimentedon 4 years ago. it's really scary actually, considering that hydrochloric acid [and stomach acid (which is also HCl, haha)] have the same pH.
just the fact that it's really acidic should tell you how much it can do to metals and such--it can be highly corrosive. it can also be used to clean tiles and the like..

If this is a collectible coin, I council care in cleaning. Improper cleaning can result in a great loss of value for the coin. Soap and water is a good start. Denatured Alcohol is a very good cleaning agent. It is very flammable so great care is advised.

My dad always says the old coke was much better because you could clean car battery terminals with it back in the 50's lol
