America's Most Expensive License Plates
8. 1913 Idaho ($13,000) - The 1913 plate was the first issued by Idaho. Back then, the state's registration fees were based on a vehicle's horsepower. Collectors note that the 1913 plate's dimensions are 15 1/4" by 6 1/4"--unusually large for an American plate.
7. 1905 Vermont ($15,000) - The 1905 Vermont plate doesn't display its year, but avid collectors know it well. The plate is one of the first made of porcelain; formerly, sign-makers created plates by baking enamel over steel. Connoisseurs admire the Vermont plate's deep cobalt blue background.
