The nineteenth state quarter belongs to, of course, the nineteenth state to join the Union, and features nineteen stars for just that reason.  Along with the stars and an outline of the state of Indiana, a race car is also part of the design because the world-famous Indianapolis 500 is raced there.

The race takes place at the Indianapolis Motor Speedway, which was built in 1909 to test cars.  Car makers still use the Speedway to test cars, but it's most famous for the races, which have been held there since 1911 every year except during the two world wars.

Indiana citizens voted on their favorite designs and Governor O'Bannon picked "Crossroads of America" from the top four designs that the Mint prepared.
