Noteworthy is the one-word answer to the question “Does the RAM provide free samples of coins?” as well as the fact that there’s a limit on the number of coins that you can hand over at shops. (From reading the linked act (I am not a lawyer), it seems that this is done via the definition of legal tender—more than 20¢ in 1¢ and 2¢ coins does not constitute legal tender, and thus shops aren’t required to accept it. US comparison.) 21:59
