OPTICAL ILLUSIONS ON COINS AND MEDALS

drachm optical trickery

Last week an article illustrated the above Philistian drachm which, when turned 90˚ the lion on the coin’s reverse becomes the helmet of the bearded man, and its paws becomes the man’s hair. I asked readers for examples of other examples of such “optical trickery” in coins.

This coin from Liberia 2001, KM # 491, has 2 images on the reverse; rotate by 180 degrees. It is shown in my book: item XI.101. Also, there are some Anti-Papal satirical medals that have 2 images.
