1. TIME FOR A CHANGE In my pocket, I have some nickels, dimes, and quarters, a different number of each totaling less than a dollar. Strangely, if my nickels were dimes, my dimes were quarters, and my quarters were nickels, I'd have the same amount of money. How many of each coin do I have?

2. STRAIGHT AND CURVY Put a digit 0, 1, Z, 3, 4, S, 6, 7, or 8 (Yes, the 2 has been straightened, and the 5 has been curled) in each empty square so that straight digits (1, Z, 4, 7) count the number of (horizontally, vertically and diagonally) adjacent straight digits, and curvy digits (0, 3, S, 6, 8) count the number adjacent curvy digits. One digit has been placed in each puzzle to help you out.
