You are given a bottle with American coins: pennies, nickels, dimes, and possibly quarters. You are NOT allowed to open the bottle. And you do not know HOW MANY coins are in the bottle. How can you find the exact amount of money that the bottle holds?

--You can weigh the bottle and any spare coins you have laying around to find the weight of an individual coin. You can count coins on the outside. Anything else within the "rules" is acceptable.
