US Quarter coins
Fifty six sandwiches, middle portion pure
There are 50 State quarters and 6 from from DC and the five territories Puerto Rico, Guam, United States Virgin Islands, American Samoa, the Northern Mariana Islands so altogether 56.
These US quarters are a sandwich of cupronickel (75% Cu : 25% Ni) with a core of pure copper.

They all have different reverse designs, are equivalent to 25 cents, and are metallic.
Update:
During 2010 - 2021 the America the Beautiful Quarters program is releasing 56 coins.
