NOTE September 30, 2023: I'm currently splitting this page off into a new section on my website, so this page will no longer be updated. The link, however, will continue to work.

I currently have this page split up into several pages, which I'm currently developing. This is what I have for information on "other" plate information:

Sticker Mania


Sticker mania is when people stick stickers all over the license plate. Typically it is when there are two stacks or more of stickers. Insert plates and sesquicentennial plates have a tendency to be sticker mania license plates, though I have spotted some other sticker mania plates.

Some plates also have stickers placed in the wrong place, either on the wrong plate or on the wrong place on the back plate.

Sometimes, but very rarely, there is the wrong sticker on the license plate.

Plates not in my collection:

Other times, plates get registered after they were supposed to be replaced.

Once in a blue moon, an undated plate will get a sticker. How does this even happen?

Flip Sheeting


Most reflective license plates have bare aluminum backs, however, some plates have painted backs. Plates with painted backs appeared to be issued in 5 runs: Late A, Late C, Early D, Mid-E , Mid-F, Late G, Early H, Mid M, and for black, no passenger plates have been found yet. Many flip sheeting plates were produced when there were old rolls of painted sheeting when a series discontinued.

It is important to note that the difference between gray and white license plate backs is very small in photos, and I'm still working on figuring out which is which.

Note May 19, 2021: I've temporarily removed the table because it is hard to use on mobile devices, the table will return sometime between now and July when I finally finish working on the other pages that I've been working nonstop on.

This plate has a blue front.

This is the front plate of the pair, which has a lot of torn sheeting. The blue color is more noticable on this plate:

The backs of the plates look like aluminum that got a coating that was transparent yellow. 1989 dealer plates had backs that were a kind of matte aluminum. So... what WERE these license plate blanks used for?

Reflective Insert Plates

I'm starting to suspect that, like flip sheeting plates, reflective insert truck and trailer plates are produced when light truck for hire bases are no longer used. I'm going to start tracking the numbers for them, though they could be error plates too.

Error Plates


There are various error license plates. Some errors are as obvious as a major mistamp or missing paint, others are very subtle and hard to identify.

Paint

This graphic base plate has no foreground paint. I don't know why, and I don't know if it is intended or an error.

Other plates have areas that missed paint because of the way they were painted.

Very rarely a license plate will use the wrong paint.

End of Sheeting

Sometimes, when a roll of sheeting is depleted, a license plate will have overlapping sheets of reflective sheeting.

Dashes

Some plates have the wrong dash.

Other plates have dashes where ther isn't supposed to be a dash.

Some plates are missing a dash. The most notable example of this is a few thousand truck plates in the BE series that were missing a dash.

Crooked stamps

Some plates that were stamped crookedly are very obvious and easy to spot.

Other plates are hard to see and you have to look very closely to see the misalignment.

Misaligned prefixes

Some plates have misaligned prefixes.

Invert Errors

A very rare error. Invert error license plates are worth a lot of money.

Broken Dies

Sometimes dies break, so there is a spot where the dies were missing.

Numbers too high

Some plates have their numbers stamped too high.

Extra Stamps

Sometimes plates have two different stamps on top of each other.

Other times plates will have something between the die press and the plate, and it will get stamped into the plate.

Mismatched Die Sets

There were multiple distinct die sets. I will list the differences between each die in each die set:

Dies Character Description
Wide 1 2 Slightly smaller space
5 Shorter bottom curve
7 Curved
Wide 2 2 Slightly larger space
5 Taller bottom curve
7 Straight
Tall Prefix 1 A Thick outline
G Thick outline
Tall Prefix 2 A Thin outline
G Thin outline
Narrow 1 W Short middle line
Narrow 2 W Long middle line
