Gerry has a large number of pennies, nickels, dimes, and quarters.

Penny = 1 cent.
Nickel = 5 cents.
Dime = 10 cents.
Quarter = 25 cents.
Dollar = 100 cents.

Jane chooses a type of coin, and Gerry calculates the value N, such that N of that type of coin are equal to 1 dollar. Gerry then gives Jane N² coins of that same type.

Which coin do you advise her to choose?
