These 2 Morgans have a plastic that is very sticky over them. The plastic will come off but the sticky glue stays on the coin. The glue on the coin on the right has turned yellow. Is the plastic going to drop the value much?   |

Bath the coin in acetone (read up how to do it). Acetone will not change the coin but will remove any organic material (including glue).

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.
