I recently acquired this 10 cent token from Company 3747 in Paris, Missouri. It has a few spots of environmental damage and some crud on it. I decided it needed conservation. The environmental damage could not be reversed, but the rest of the piece looks much nicer.
This is what the piece originally looked like:
Here is the token after conservation:
I soaked the token in Acetone and, under a stereo microscope, used blackberry thorns to dislodge the dirt and crud.
Thorns are great tools for this type of coin conservation. They have very fine points and are soft enough not to scratch the coin (if you’re careful). A friend suggested rose thorns work better, but I have more blackberry bushes in my neighborhood than roses.
