It was made in the 1680s in France

Despite what we think of the French (mostly justified), 1680s France was not a pre-literate society.

If this toy-coin (made for games) was really depicting a flying-saucer witnessed at the time, we would have to believe the following scenario:

A citizen of France witnesses a flying saucer and says to himself, "how can I best tell the world about this event... I know! I'll put it on a toy coin!"

Pardon my skepticism, but, yeah, right.

A citizen of France witnesses a flying saucer and says to himself, "how can I best tell the world about this event... I know! I'll put it on a toy coin!"

I think the toy coin has a picture of a toy on it... an early form of a whirlygig. A fan with a handle you can spin between your palms and cause it to fly up in exactly the manner shown.
