I've been looking for one of these off and on for a few weeks. It looks really amazing and is absolute proof that in the 1600s the French witnessed enough UFO sightings to decide to put some of what they saw on coins.
This is a French jeton minted in somewhere between 1856 to 1680, a coin-like educational tool that was commonly used to help people count money, or sometimes used as a money substitute for playing games. It is about the size of a U.S. quarter-dollar and similar to thousands of other jetons with different religious and educational designs that were produced and used in Europe during the 16th and 17th centuries. It appears to commemorate a UFO sighting of a wheel like object. Some researchers feel it represents the Biblical Ezekiel's wheel. The Latin inscription 'OPPORTUNUS ADEST' translates as 'It is here at an opportune time".
If you are lucky you can find one on Ebay (Click Here) for anywhere between $20 US to $500 depending on the sellers asking price and condition of the coin. I heard from a guy who won a similar coin that he got for $45, because it was just listed for a few hours when he hit the buy it now button, so timing and luck are everything. Happy hunting.
