possible coins: penny (P), nickel (N), dime (D), quarter (Q), half-dollar (H), dollar (1)

PN: (1 + 5) - 13 = -7 (not possible)
PD: (1 + 10) - 13 = -3 (not possible)
PQ: (1 + 25) - 13 = 13
PH: (1 + 50) - 13 = 38
P1: (1 + 100) - 13 = 88

ND: (5 + 10) - 13 = 2
NQ: (5 + 25) - 13 = 17
NH: (5 + 50) - 13 = 42
H1: (5 + 100) - 13 = 92

DQ: (10 + 25) - 13 = 22
DH: (10 + 50) - 13 = 47
D1: (10 + 100) - 13 = 97

QH: (25 + 50) - 13 = 62
Q1: (25 + 100) - 13 = 112

H1: (50 + 100) - 13 = 137
