If the question concerned the number of combinations of three different coins, the answer is 23-1 = 7.
If the coins are a,b,and c, the combinations are
a, b, c, ab, ac, bc, abc.
If two of the coins are the same there are only 5 combinations and if all three are the same there are 3.
There are 5C3 = (5*4*3)/(2*1) = 30 combinations.
