<p>[QUOTE="desertgem, post: 1556671, member: 15199"]It looks in the photo like you described "glue" or glued paper such as paper tape. Unfortunately there have been several common glue formulas in the last 90 years. Some are more water soluble, some require heated water, some are alcohol soluble, some are acetone soluble, some are naptha removable ( Ronsen lighter fluid). None of these should react with your metal coin unless rubbed, scrubbed, or left standing for long periods. If it is modern glue, it could be acrylic or epoxy which is almost impossible to remove. I wouldn't use goo-gone or similar as its ingredients are not as well identified. Remember the surface beneath will probably look different than the rest, but this is due to toning exposure and not necessarily the agent. I would rinse with acetone at the end.</p><p><br /></p><p>Since it is not my coin, and I am just seeing photos, it is hard to say what to start with, and I am sorry I can't say which. IMO.
