Pocket Change (Posted on 2013-07-30) Difficulty: 4 of 5
A friend of mine, Sol announces that he has a number of coins in his pocket that add up to precisely one dollar. When he tells me how many coins he has, I ask if any one of them is a half-dollar. Sol tells me "no". I realize that I can't tell for sure what coins he has, because there are six different combinations that produce precisely one dollar.

How many coins does Sol have in his pocket?

A seventh way with 16 coins is 3 quarters, 3 nickels and 10 pennies.
