I have a 1932-s Washington Quarter that has black spots mainly on the obverse. The coin could have a high grade if not for the spots. Can anyone offer suggestions from the photos as to what is the best way to proceed to getting the spots off. Is it worthy to send to NCS? Thanks so much!
That coin looks awfully shiny doesnt it? Like someone has already tried to worsh it. If it were mine id start with acetone and maybe xylene since it appears to have already been cleaned. Im afraid the damage is done though, and it might be too far gone already, to "fix" it. I am by no means qualified to give instructions on how to remove said spots, as ive never encountered/experienced such a problem. So a grain of salt should be prescribed here. Really sucks that its a '32s though @Insider will probably have a good opine
My greatest fear here is, those spots are what the previous Amateur Hour cleaning was unable to remove.
Too Bad. I saw a 32-D this weekend in a NGC Holder graded G-4. The rims were almost gone and the lettering was worn down into what was left of the rims. I'm not sure how it even Made G-4 ?
Those look like the type of spots that are etched into the surface of the coin. So even if you remove them there's going to be noticeable environmental damage in the area where the spots were. Imo this isn't a coin to send in to be conserved as it's value really isn't going to improve you'd just be sinking money into it for nothing.
This is just what I was thinking. I'd also like to see a close-up photo depicting the mint mark. If it looks lousy & is in a depression, then the coin is probably a US mint product. (At least that is what I recall about the 32 D & S coins).
