So, what is the purpose of this and why is only one plate issued (do you mean one of the plates on the car has to remain as ‘originally’ issued?)?
I thought that ‘over the pond’ you could choose you licence plate anyway, so long as it wasn’t rude!
There was a time, when I was a child, when nearly every state in the USA issued two plates--front and rear. Many of them did this annually! So, you had to replace your plates each year.
After a while, New York (where I grew up) changed it so that they only issued a tiny metal "year plate" that fitted to the corner of the license plates to update them for the current year.
Then, as they say, "it's all about the Benjamins": it became a money issue. (Note for those unfamiliar: Benjamin Franklin is on our USA $100 bill) Some states only issued a rear plate, saving the states millions of dollars each year. Renewals came not in the form of new plates, but of little stickers.
But there are massive costs in each direction: if you order a new car in a one-plate state (Michigan for example) you will not get a front license plate "system" which, though mostly made of plastic, is a big contrivance that is affixed to a bumper somehow. When I bought my father a 5-year old car in Michigan some years ago, we had to pay a fair price online to get a front license plate assembly for his 2-Plate Massachusetts.
Some interesting reading, as it also brings into the equation photographing cars at borders and red light cameras, etc.:
