How To Remove This (Whatever It Is) From A Coin

OAKSTAR

A little help please.

braddick

I would soak it in GooGone and follow that up with letting it sit in a squirt of WD40.

This would be glue of some kind, with the brownish-transparent stuff being the actual glue and the white stuff being remnants of whatever surface the coin was glued on to.

Epoxy glue - "superglue" - comes off nicely in acetone.

Pure acetone is the way to go. Soak it for a while. Good luck.

Acetone in a covered glass container since it evaporates quickly with frequent changes in the acetone. Or, you can just spend it since that cut on the obverse from a paper roll end crimper keeps it from being worth more than face value.

Kurisu

I bet a few days of xylenes or maybe acetone and or maybe a bit of toothpick attention...but neither is going to take care of the ring of death on the obverse

If it's soft, like rubber cement or a sticker, you can peel this off using your thumbnail.
As others have mentioned, advanced methods and costs are not needed since it already has damage.

There's a decent chance that's normal Elmer's glue. If so, acetone will NOT help. Elmer's dissolves in water, not acetone.

machine damage on obverse - spend it (unless you feel it a cheerios)

Was probably super glued to the sidewalk.
Looks like concrete residue.
Acetone removes super glue.
Or just save time and spend it.

No (zero) chemicals, if at all possible gents. Whatever it is, contact cement, glue, rubber cement, 2 part epoxy, super glue, spray on lacquer/enamel, constructive adhesive, liquid nail, etc.. Always try a hair dryer first. And don't touch that coin right away. Man, it gets HOT!!

@Kurisu was right about two things, a toothpick and the ring of death.

I could see it wasn't a Cheerios dollar before I removed the adhesive. I only wanted to remove the adhesive to check for a speared eagle.......................no speared eagle. :'(

you should put it out in a parking lot and see how long before it shows up here again

Sure, I'll do that.

I personally would prefer applying chemicals to coins rather than heat. I know acetone won't harm the coin, but heat - especially if it becomes "too hot to touch" - is going to accelerate oxidation, especially for reactive alloys like manganese-brass. For a circulated, already-oxidized coin it's fine, but not if preserving lustre is a goal.

Well, I'm not a chemist or metallurgist but your point is taken.
