Musee Mecanique, the old-school penny arcade

Today, WalletPop takes you to San Francisco's Fisherman's Wharf, where inside an unassuming shed facing Alcatraz Island, you'll find one of the most unique attractions in the country: Musée Mécanique, the "mechanical museum." It's both a virtual temple to spare change and the product of thrift where a pocketful of quarters can transport an entire family to the early 20th century.

Not only can you see the Musée on a dime, but it runs on one, too.
