Did you see my other post? I made comments about vinegar there. It will get rid of the corrosion but there will be a rough, or maybe matte is the best word, finish to it. The color will be a whitish silver rather than the normal silver gray color.
Here's what I would suggest if you are curious about vinegar. There are two different tests to try out. First, get a shiny new Jefferson nickel (since it has the same composition as a Buffalo. It doesn't have to be brand new, just make sure it is in nice condition with a decent amount of luster left. Put that in vinegar for two to three days and look at the results. That will give you an idea of the effect of vinegar on a coin as far as condition is concerned. Essentially it is the "control".
Second, find a corroded Jefferson nickel. If you can't find one and don't know anyone with a metal detector I'd be willing to send you a few in the mail that I dug from the ground if you PM me. Now try the vinegar treatment on it. Once or twice per day you will need to wipe the coin to remove the corrosion that has been loosened. The coin will turn reddish at first, then pink and silver, and if you give it long enough (2-3 days normally) all the pink will be gone and you are done! The end result will give you a good idea of what the final result of the Buffalo will be.
