Problem 29214 just answered the question. Basically start with five cent nickels, and see which numbers you can eliminate at every five (5, 10, 15, 20...) Then add a seven cent piece, and then mark off every 5 which you can get to by adding five cent pieces (7, 12, 17, 22...) and keep going adding another seven cent piece and then adding nickels.
