I'm honestly not for sure, I was wondering if there was a way to test it or some sort of dead give a way. the thread pattern seems to cover a lot of the face of it. I've not tried to scratch it off or anything in fear that I would damage the coin. I was wondering if it was glued to a kids piece of artwork or something a long time ago but there doesn't seem to be any residual paper or glue anywhere else on the coin. As a side note when running my fingers over it, it doesn't seem to have a glue like texture.
