Sticker residue on a St. Louis Worlds Fair medallion

This 1904 souvenir is in such nice condition that it is a shame one side has what appears to be the remais of the gum from a price sticker (and who'd be that dumb) .

Any suggestions for lifting off the residue without spoiling the otherwise excellent example.

GooGone followed by soap and water rinse.

 

If it's silver, acetone or MS70 - no promises on grading when done obviously. If it's not silver, I don't have any idea of what is safe.

Try soaking in distilled water for some time and see what comes up first?

 

Zippo lighter fluide

 

Goo-gon is a US product, but I expect the shops do stock lighter fluid still. Possibly.

I suspect it is gilt brass.

 

I have no idea what the value is on this. Would it be worth sending to NCS?

 

I'd sooner seal up my cat in a plasic box than seal up my coins and similar objects.

Let alone waste money on having people tell me what I can see for myself.

 

I sure that were you are that they have a similar type product to remove stickers, and adhesive residue. Acetone, lighter fluid, or even a quick hit with WD40 or that type of liquid removes most oil based adhesive. Craft stores and art supply stores carry them or on line.

 

I think I'll try a spot of acetone first.

 

Just understand that once the residue is removed you may still have a color difference where the sticker was.

 

None of the above boil distilled water and soak. Glue and paper will come off without doing any damage.

So boiled distilled water would be the first item you would use to remove glue like substance correct?

 

Well if it IS gilt over copper there is a chance the gold may not show much of a color difference.

 

Nope, clear as day my friend, clear as day!

 

Sorry to bother you but I have a question I thought you could answer if you don't mind--our family found a small folder with 18 Greek coins from 1869 to 1926 in our relative's belongings and all of them are glued to the red paper backing with glue that is stuck to the back of the coins. The oldest 4 leptas are copper and are looking pretty bad. The rest I believe are a copper-nickel alloy leptas and those look like they have nice details. Will this distilled water method work? If not what should I do?---update no need to answer unless you don't agree with BadThad from the link above--no idea where to get xylene, if I need it...
