Cortes reported that Montezuma drank 50 goblets of (non-sweetened)
cocoa beverage before entering his harem.

a goblet of cocoa was expensive to make in pre-mechanized society.
Even if the laborers were nominally slaves, they had to be fed,
clothed, housed, etc. In fact, the houseservants of a sovereign are
normally well kept.

Is it possible to estimate an equivelant 2007 value of a goblet of
Monteuma's cocoa drink?
