Monetary currencies are just a generalized issued tokens, whereas movie tickets and postage stamps have a more limited use. Then, under "Issued Tokens" you would use a Unit that matches what they are issued for, with monetary currencies in part being created for the purpose of having a unit, i.e. they create their own unit, whereas the unit for movie tickets is "seat" and postage stamps is a monetary currency.
I would like to exercise modeling of FoodStamp. How would you currently model an Offer(s) which gives choice of receiving certain amount of food after 'paying' for it either with $$$ or food stamps?
