One of the catchphrases (spoken in an Italian accent) from the very popular British TV comedy Allo Allo (set in occupied France) is "Here is another French mistaka". Here's another "mistaka" from the latest issue of Richard Lobel's CoinCraft's "the (sic) Phoenix"

The coin has a face they say, and yes, you can see what looks like a Pokemon figure, unfortunately it is a denier viewed upside down! What it actually shows is a building. Richard Lobel has had many years of coin trade experience so I trust this "mistaka" was made by a staffer. I was later advised by an expert on medieval French coinage that the coin is not even from France but is a Frankish issue from Greece!
