The MG and MGX prefixes were first used in 1926.
At this time, municipal, county, and state government became unique types.
Until 1958, municipal commercial plates used a different series than municipal passenger car plates, incorporating the X code for commercial.
This practice was discontinued with the tan base in 1959.
1959-1977MG-100A - MG-999Z
MG-A100 - MG-Z999
MG-1000 - MG-9999
100MG-A - 999MG-Z
The 1959/1977 Municipal plates have several different patterns, starting with MG-100A, then MG-A100, MG-1000, and 100MG-A.
Thanks to John Walters for the information on the proper sequence of these.
STICKERED 1973Lee Madigan
These are remakes - made in the mid 70s - of the early 60's issues.
The only known pattern on the 1977 base is MG-000A. These would be remakes (or re-plates ?) of the early 60's issue.
1979 BASEMG-1000 - MG-9999
MG-10AA - MG-99ZZ
The 1979 base went back and re-issued the MG-0000 plates, and then continued where the 1977 base left off in the MG-000A series (somewhere bewteen MG-999G and MG-100M).
By the early 80s, MG-999Z was reached, and a new series started at MG-10AA.

1992 BASEMG10000 - MG50999 (?)
The 1992 graphic issue brought a new numbering pattern - 7 digits starting at MG10000.
There are also re-issues (or remakes ?) of the earlier series.
Some municipal plates have stickers - but it seems to be arbitrary.
When stickers are used, plates are usually "valid" for 4 years.
