What happened? The water evaporated and as that occurred the acid became more and more concentrated. Finally the water was gone and the straight acid was left on the coin.

Or Nic-a-date, but I heard vinegar doesn't leave as bad of a stain

Those Nickels are probably in really bad shape by now. They were almost worthless before your experiment, and worth less usually after such treatments. Now add in the cost of the Vinegar, more Vinegar, gas in your car to go buy the Vinegar, your time and you now have a massive investment in coins worth almost nothing.
Reminds me of a neighbor that drives a few hundred miles to buy farm fresh eggs each weekend. AND he gets them for only a little more than most stores but they are fresh or so he says.

Two of them could, might be worth something but if you can not sell them for what they could, might be worth, then just a good experiment. |

Always use a COVERED container when soaking coins....no matter what the solvent is. You never want your solvent to evaporate. When that happens the dissolved solute is concentrated (acetic acid in this case) and can redeposit on the surface or worse, cause severe damage. This is a rookie mistake that can make a bad situation worse. DO NOT LET YOUR COIN SOLVENTS EVAPORATE!

@BadThad - does this applies to acetone too?

^ Yes. Just cover it with clear wrap if you want to soak the coin. I just dip it, wipe it with cotton balls or Q-tips, and then rinse it off with water. Then re-dip the coin and let it air dry.

clear wrap won't dissolve in acetone? never tried this before, so I'm curious about the clear wrap in acetone.

Use the clear wrap to cover the dish the coin and acetone are in if you are going to let the coin soak for a period of time, not wrap the coin itself.

Acetone is very volatile, it must be used in a sealed, glass container. A baby food jar would work great. Keep is away from ALL plastic as it will melt most plastics.
After soaking, rinse with fresh, clean acetone. There's no need to use water.

For acetone, I use the canning jars with rings (Ball or Kerr jars). Instead of using the regular lid inserts or a pickle jar lid (they have rubber seals which the acetone will transform into goo), I use aluminum foil. With the rings it makes a sufficient seal to prevent too much evaporation.
