Pre-1932
Before Colorado license plates had explicit county codes (this practice began in 1932), they were issued in blocks to each county. Evidence of this goes as far back as 1916. Below are any examples of pre-1932 Jackson County plates the museum has been able to acquire.

1932-1958
In 1932, Colorado began using 1- and 2-digit prefixes to denote county of issuance on its license plates. They were numbered 1-63 (for 63 counties), and they were ordered based on population in the 1930 census. 59 used to denote Jackson County plates because it had the fourth-lowest population in the state at the time.
