skelly423 Valued Member Canada 187 Posts	Posted 08/04/2017 07:28 am I have a 1937 nickel where the reverse is covered in what looks like metal bubbles that protrude out from the surface of the coin. The obverse is completely ordinary and unremarkable. Initially I thought it may be acid, but acid bubbles would erode into the coin, not protrude out. Is this a production issue, or is it likely post mint damage? Either way, I'd be interested in your opinions as to what caused it. If it's a production issue, any thoughts on what it's worth? Thanks Report this Post to the Staff

Very interesting. Edit: I took a second look at the zoomed in image and now I'm seeing transparent "pebbles" over the top of the design. Optical illusion on my first look maybe. I think it's glue.

Spence Moderator United States 34416 Posts	Posted 08/05/2017 12:25 pm @skelly, could that be dollops of glue stuck on the surface? Usually they are clear and so the underlying coin is not as toned as the surrounding surface. However, on your coin, the color is closely matched. Maybe try soaking the coin in acetone to see if you can remove the bumps?

The Awesome Guys Coins Valued Member Canada 150 Posts	Posted 08/08/2017 8:38 pm I wouldn't suggest soaking the coin in acetone, because it would damage the coin and lower its value. Instead, I suggest you put the coin in water and so the glue may melt away Report this Post to the Staff
ace_ftw Pillar of the Community Canada 1747 Posts	Posted 08/09/2017 10:27 am Pure acetone will never harm the coin, you can do a search on the forum about the proper use of acetone baths. water will not dissolve glue on the coin, but acetone will, and will leave the coin unharmed. however if this is glue, the spots would most likely leave the coin spotted as the uncovered area would be toned differently.
