I bought this 1953 S Franklin half that is really nice however it has some spots on back. What caused these stains? I was guessing water but would expect some kind of corrosion with that. Any help would be appreciated.

Interesting. I would want to see what an acetone rinse would do.

Here is a few pictures taken straight on. I was thinking of an acetone wash but wanted some opinions as to what it was.

I have never done the acetone soak before. I have done a little research about it and have a small glass bowl and acetone, how long do you guys recommend I soak it for?

If you have never used acetone before, you may be surprised at how rapidly the acetone may evaporate and leave your coin high and dry in the bowl. I use a small glass bottle big enough to hold the coin and put enough acetone in to cover the coin. I use a pure Chinese bristle brush with the bristles attached to the brush handle by a metal ferrule. Don't use a plastic ferrule as the acetone will dissolve it and it will deposit on the coin. I agitate the bristles over the stains being very careful not to touch the surface of the coins with the metal ferrule. Just use the bristles to wash the stain with the bristles.
How long should you soak? I have set coins to soak and forgot them overnight and simply put some fresh acetone the next day and refresh the bath. Word of advice: don't dispose of any large quantity of acetone by pouring it down the sink unless you wash it down with a large amount of water.

Well I soaked it in acetone and it did not change the spots. The toning came off. I soaked it for 15 minutes then changed out the acetone and did another 15 minutes.

As long as the Acetone did nothing, next try just plain distilled water. If that does nothing, just try some dish soap and water. By this time if all has failed, you may want to just try some jewelry cleaner. The stuff sold at Walmart to clean jewelry. It is not highly recommended for coins since it usually takes some of the surface Silver off. However, buy now you've soaked it in Acetone, water, soap, etc. Not much left to loose. Not sure how much you paid for this coin but hopefully not to much. After a bath in jewelry cleaner it will always be a cleaned coin.

Shucks. You gave it a good shot but those stains just wouldn't budge. It would be a shame to lose that beautiful luster. Just fill the hole in your album and enjoy that beautiful obverse.

Hoxsie454, I'm going to follow your advice. The pictures don't do the coin justice. The luster is really nice. I bought the coin for 8.00 dollars.
