Interesting Small 1851 Bronze Crystal Palace--Obverse/Reverse Dies Nearly Identical #S225
Close study looks as if the dies are almost but not quite identical. Very interesting that they would not be neither completely different (as you would expect) or exactly the same, rather than so similar. I have studied the medal trying to see if the same die could have resulted in these slightly different images. Interesting and scarce, but inexpensive medal from the first world's fair ever held.
