I estimate this plate to be from the very early 1950s.
Another format was later introduced on 6x9 plates with stacked prefix numbers. This plate is 6-1/2" x 11".

Same, probably from a highway maintenance vehicle  4-digit State plate. These had up to 5 digits in the general motorpool (5- prefix), for example 5-12345

'State' plates were one of the last types to be completely replaced in the general reissue. Plates of this style were still use on some state vehicles such as buses, tractors, etc. for about 4-5 years after the general reissue.
   


State Service Bus
Click to see this type in useThese plates are used on state-owned buses which do not charge a fee for transportation.

These plates are typically used on buses belonging to the State Vocational schools, the State University system, and prisoner transport buses.

This type started sometime in the 1970s. 

Beginning in 2016, as with pretty much all of the other formerly all-numeric types these plates now use the AB-12345 numbering format.
