Small Collection Of British Coins.

@arbu, first welcome to CCF. Second, I would echo @sel's advice, with the possible addition that depending on the type of glue, you might find that soaking in distilled water might be more effective if the acetone soak doesn't work. In the end, you will most likely find that the areas that were previously under the glue will be less toned than those that were left out exposed to the elements. You should resist the urge to strip off all the toning or polish these coins to make them uniform. Nice group of coins!

Thanks. I'll get some acetone. I do have some nail polish remover but from the label I see it has some extra chemicals which might not be too good for the coins.

I think they have been polished on the non-glue side. Still, they are of a good age and I would quite like to put them in a frame to have on the wall. I only just looked at them last night for the first time in probably ten years and it would be good to have them out more. The best thing would be a double-sided glass frame so that they could be taken off the wall and the other sides seen, but I don't really see much like that online.
