If the acetone doesn't loosen it, try temperature extremes. The adhesive will expand and contract much faster than metal causing it to shear away. Try freezing it. that will also make the adhesive more brittle. If it's been on there a while, you'll still see traces as the areas under the glue were protected from corrosion.

Lets hope some of the chemistry in the glue has not INorganically reacted with the surface of the coin. IF that has indeed happened, the coin itself may end up being permanently stained.
Whatever the case, the sooner the glue is removed, the better.

 Oh I am so hoping they aren't damaged. I just acquired quite a few coins from a family member and 3 of the Morgans have this plastic. Guess I am going to have to learn more on soaking them. I have never cleaned any of my coins before. |

The acetone should remove it. You may need to do one soak to remove most and then a fresh bath to remove the remaining residue. The acetone will put the adhesive in suspension and make the whole coin sticky. The second will do the final clean. Don't rub just allow to evaporate off the coin

Be sure to use pure acetone not nail polish remover. You can get pure acetone in the paint department at Lowes and Home Depot.

Yes, definitely acetone, not polish remover. Good luck!

They are common date/mint mark Morgans. Give 'em a bath in acetone and see if it works.

How did I do? Thank you all for the advise. Now if I can figure out the VAM.   |

Nice.  1881-S has no value-added VAMs so attributing it is an intellectual exercise. Look carefully at date and mint mark for doubling with this issue; those features will lead you to the majority of the possible VAMs. I think I'm seeing a right-tilted mint mark which will narrow it down greatly. |

Thanks SsuperDdave. I think I found it as a VAM 5. I'm only trying to identify to learn. I'm going to post it in the VAM section to see if I got it right. |

I really like the color of the 1881-S.

Acetone will not remove all types of plastics or glues, despite the powerful solvent that it is.
As a desparate measure flash freezing may help, to take advantage of differential contraction rates between the silver and what happens to be stuck on the coin.
Ultrasonic cleaning may help, but I seriously doubt that this approach would be of any effect.

I would give the first one another long soak. Could just be me, but I still see some residue.

If acetone doesn't cut it, benzene may be tried -- probably want to wear rubber gloves though.

Look at other discussions on acetone. I cannot get the search option to work or I would post links. You do not have to go to a paint department. Wal-mart or the dollar store sell it. It is labeled as pure acetone. Do not get fingernail polish remover if it has added dyes or perfumes - if the bottle says pure acetone - it is fine. I have used it on hundreds of coins, and conducted an evaporation test on glass before first using it (to see if here was residue left behind when the acetone evaporated). Don't be alarmed when you read the ingredients label on a bottle of "pure" acetone and you see a very minute additive. The additive (Denatonium I think) is the most bitter tasting chemical known, and it is potent enough that extremely small amounts make it so people won't drink the acetone. The chemical is added in such small quantities that the acetone is legitimately considered pure (again there was a discussion on CCF about this, but the search just freezes on me or the link would be included in this post.) Here are examples of two I have bought before. The typical nail polish remover-shaped bottle was from the Dollar Store, and the other one is from Wal-mart.   |
