These large silver coins from Jan van Brienne were probably an attempt to introduce a larger value, but apparently not really accepted by the population, so that the minting was quickly stopped and the type can be called quite rare. Metcalf believes that production may have been after 1212, but before the ill-fated Fifth Crusade to Egypt in 1217. The Knights Hospitaller would have made use of it in any case. Metcalf Ash. p. 74.
