open mike,

#25 on your list is obviously wrong. With coins in denominations of 1/2, 1 cent, 2, 3, 5, 10, 20, 25, and 50 cents, and 1, 2.5, 3, 4, 5, 10, 20, 25, 50, and 100 dollars ( all US coins), there is no limit to the amount that one might have and still not be able to make change for a dollar.
