This is a trick question and found often in joke and riddle books (my 4th grade daughter loves trying to trip me up on problems like this).
...
First, with US coins coming in 1, 5, 10, 25, 50, and 100 cents denominations, and two problem conditions:
...
US currency (so no trick of using foreign coins of different values)
Only two coins allowed
...
The answer HAS to be: a nickel and a quarter.
...
The stipulation that ONE (my emphasis) is not a quarter often throws people off; however, it only means of the two coins in question, one of them cannot be a quarter. The intuitive trick is to go, "a ha!, the other coin is the quarter, the first must be the nickel."
...
This trick is based on words and logic, not on mathematics...
...
cheers,
