Constantine I as Caesar from Lyon with old tag

[Victor]

It's neat having an old collection tag, except when they glued it to the coin.    I also don't have the provenance, so the tag is doubly worthless. I have another coin with the same type tag and I am soaking it in acetone to see if it will come off; but no luck so far.

Strange way to treat a collection.. seems like the kind of thing a museum might do more than an individual, perhaps, but who knows. Maybe heating it up a bit would soften the adhesive if acetone doesn't do the trick.

Could be worse, such as Gonzaga "countermark", which I just read is more than just a stamp - it's a silver inlay.

Please excuse the NSFW example!

Yes, it could have been a museum collection. I wouldn't mind the Gonzaga countermark as much, since it at least has a provenance...my coin just has a tag glued on by some anonymous jerk!    I actually have several of these with old numbers glued on.
