given that its suitability for forming a currency are so strong - it does have worth as having the potential to form a new currency if for some reason one were needed. Bulk dried beans would work short term, assuming food shortages etc from whatever caused a new currency to be needed, but before long someone would want something to use as money that wasn't directly consumable. I think perhaps its this fact that it is so suitable to form the basis of a new currency that gives it strength and stability whereas other more directly man made money systems are less durable
