Nebraska has held much tighter control over specialty license plates than Iowa, but in the past few years that has loosened. Now Nebraskans can have specialty plates for Creighton University, the state’s sesquicentennial (2017), and members of the military.
But coming soon, developed by the Nebraska Corn Growers Association, is a colorful way to glorify corn. Soon, residents from Rulo to Scottsbluff can have a giant ear of maize draped over the leftmost quarter of the license plate.
The Omaha World-Herald article linked at the top notes that Nebraska will have a new default plate in 2017, changing every six years, while Iowa continues cycling through the reverse alphanumeric that started in 2012 and still uses the 1997 design. What won’t change in Nebraska, as far as I know, is the use of numbers for counties based on vehicle registrations from 1922.
EDIT: Sesquicentennial year corrected.
