Does anyone have any secrets or solutions to cleaning up (dup up) Buffalo Nickels. These nickels were dug up in the 60's & 70's. I have about 80 of them and most have no dates and are dark and rusty looking. I want to try to bring the date back on them, but the solution turns very dark when applied. Any help will be appreciated.

You could try soaking them in white vinegar. That will lightly etch the entire coin surface and in many cases will expose the date. I wouldn't expect it to darken the coin. Worth a try IMO!

My nickels have been soaking in white vinegar for 4 days. They're trying to loosen up, but the vinegar has a blue tint to it, should I change the vinegar? Why blue?

Change the vinegar every couple of days.I would even try to loosen the stuff up with a q-tip first and then change the solution.


I know I'll find one in this roll!

OK, thanks. Wasn't sure if the vinegar would lose its potency. I guess it does.

Vinegar is dilute acetic acid which, although a weak acid, does gradually dissolve the copper and nickel metal from the coin surface. The metals are converted to acetate salts and those substances are bluish-green in color, so the vinegar solution gradually turns blue. The acetic acid is used up as the metal is dissolved, so you must change the vinegar in order to have the process continue. You need to keep checking the coins and decide at what point they are "ready". If you wait too long even the major details of the coin will start to disappear.

Please post some photos of your treated nickels if you can. Hopefully you will find some better dates among your coins.

(Whoo-hoo, 2000 posts! I'm giving myself a banana dance to celebrate! )

What great info on the blue tinting of vinegar. I wish I had a camera, but thats one thing in my life that I never had interest in. I can see now that a camera is pretty much a must on coin forums. I guess I'd better get interested. Will have to do alot of reading. Congrats on your 2000th post.

The white vinegar is doing a fantastic job so far. I've got dates from 1913 thru 1937. Only 1 with a MM so far, 1929-S. I've added 4 "V" nickels to the mix and one is a 1912 something. Its either a D or S or a die chip. Time will tell.

Its not, its a D. Got alot of the crust off yesterday. Looks like its filled in though. I don't know if they're common or not, but I'm pretty sure its not coming off. I guess its a die chip.

I soaked a few 'dateless' buffs in vinegar over the weekend and checked them this morning. I found a 1914, 1917, 1918S, 1920D and a couple 1919's.

There were three 1920 and two 1927's also.

I've got another batch going in today. Six with mintmarks.


Oldest Roll/Loose Finds:
.01 - 1904 IHC
.05 - 1925 Buff
.10 - 1952 Rosie
.25 - 1957 Wash
.50 - 1918 Walker
