WCE-Outstanding Small Prooflike Landing Scene Medal & Ribbon
The medal is about the size of a quarter, aluminum and with an eagle and ribbon hanger, Columbus on one side and a landing scene on the other. The scene is different from most in that Columbus and crew are still in a rowboat not yet onshore.
You can see a mark on the landing scene side above the "R" in America. It appears to be a defect in the planchet rather than post-minting damage.
