Since it is illegal to deface United States currency, including coins, you cannot cut a dime in half. Furthermore, you cannot have a negative number of either kind of coin. Therfore, 
must be a positive integer, and therefore 
must be at least 1. Furthermore, must be an odd number. Since 65 divided by 5 is 13, 13 is the largest value may take. Hence:
\ =\ \{x\ \in\ \mathbb{Z}\ :\ x\ \text{mod}\ 2\ =\ 1\ \large\ \wedge\ \LARGE\ 1\ \leq\ x\ \leq\ 13\})
