Gold

Gold is a recurring element in the show. Prince John has the Sheriff of Nottingham collect it from villagers, Robin often steals it and returns it, while the bandits steal it until Robin steals it back from them.

In The Invisible Gold, there are actually silver/copper pieces mixed in with the treasure chest, but the cast only refers to it as 'gold'. The Prince counts "one thousand, three hundred, four-score and thirteen" then "fourteen". As "score" is twenty, "four-score" refers to 80, so he counts up to 1,384 pieces.
