According to the US Mint, the quarter dollar is 1.75mm thick.
1.75mm x 1cm/10mm = 0.175cm
Save
0.175cm x 1in/2.54cm = 0.0689in
1in/0.0689in = 14.5 quarters to make a stack 1 in high
Obviously you can't stack 14.5 quarters. 15 quarters makes a stack 1.03in high. 14 quarters make a stack 0.965in high.

If you mean, "How many nickels make a stack 1 inch high?", the answer depends on whether you're using US or Canadian nickels. Coins are measured in mm so you need to know that a US inch is 25.4 mm US nickels are 1.95 mm thick so you'd need 25.4 / 1.95 = 13 coins, almost exactly. Canadian nickels are 1.76 mm thick so you'd need 25.4 / 1.76 = 14.4 coins. You can't have 0.4 of a nickel so you'd need 15 of them to make a stack at least an inch high.
