It's also in A Christmas Carol. I had forgotten all about that one and I have several books illustrated by Arthur Rackham. https://victorianweb.org/art/illustration/rackham/7.html

I remember in the musical Jesus Christ Superstar, Judas refuses to accept the money given to him for disclosing Christ's location. "I don't want your blood money." I really like that movie for the music and acting, but especially love the way the beginning and end are framed by "real" scenes where the actors arrive and leave. Another wonderful Norman Jewison film.

I wonder if that's related to dancing a jig...if that was considered a 'trick' move or not.

The European/colonial contact with Mexico was from Spain, on Brazil was from Portugal. Different countries, different languages. Real in Spanish means royal. Other countries have currency terms related to their royalty, mostly the crown as a monarchistic symbol. England used the term "crown" for specific coins at various times. In Scandinavian countries, it's the local form for crown - kroner, krona, krone. The Czech Republic still uses koruna.
