Bought this at a local coin show for $14! I have no idea what it's really worth though. Thought I might run it by some of you guys. It says 'Andreas Vesalius Bruxellensis" on the front of the medal. It's in kind of a cool holder too, was told it was a "screw top" holder.

Cool medal. I figured you getting that for $14 was a steal... but it seems like that may be all that it's worth.
