As popularity grows, the prices reached for the most expensive plates are always increasing. As of 2008, the record price for a number plate is £397,500 paid at auction in September by an anonymous buyer for the plate S 1. This was originally owned by Sir John H A MacDonald, the Lord Kingsburgh and was Edinburgh's first ever number plate. Car design entrepreneur Afzal Kahn paid £375,000 on 25 January 2008 for F 1 previously owned and sold by Essex County Council and affixed originally in 1904 to the Panhard et Levassor of the then County Surveyor. £330,000 was spent on M 1, sold at auction in Goodwood on 7 June 2006.

Because his license plate is APRIST - short for apiarist, a fancy word for beekeeper.

Lots of people don't get it, because it's not a very common word," said Clark, who keeps honeybees in the backyard of his Old Louisville home. "Every once in a while, somebody sees is and asks me about beekeeping and honey. But the whole point of a vanity plate is to create a word which is just like the real words but is itself a puzzle, so when you're driving down the road, it's 'Oh, yeah, I got it!'""

The first series of number plates were issued in 1903 and ran until 1932, using the series A 1 to YY 9999. The letter or pair of letters indicated the local authority in whose area the vehicle was registered, for example A - London, B - Lancashire, C - West Riding of Yorkshire. In England and Wales the letter codes were initially allocated in order of population size (by the 1901 census) whilst Scotland and Ireland had their own sequences incorporating the letters S" and "I" respectively, which were allocated alphabetically: IA = Antrim, IB = Armagh, etc. When a licensing authority reached 9999, it was allocated another two letter mark, but there was no pattern to these subsequent allocations as they were allocated on a first come first served basis. There are three interesting anomalies where a zero has been issued - The Lord Provost of Edinburgh has S 0 and his Glasgow counterpart has G 0 while the official car of the Lord Provost of Aberdeen has RG 0. In addition the Lord Mayor

In 1963, numbers were running out once again, and an attempt was made to create a national scheme to alleviate the problem. The three letter, up to three number system was kept, but a letter suffix was added, which changed every year. In this scheme, numbers were drawn from the range AAA 1A to YYY 999A for the first year, then AAA 1B to YYY 999B for the second year, and so on. Some areas did not adopt the year letter for the first two years, sticking to their own schemes, but in 1965 adding the year letter was made compulsory. As well as yielding many more available numbers, it was a handy way for vehicle buyers to know the age of the vehicle immediately. At first the year letter changed on 1 January every year, but car retailers started to notice that buyers would tend to wait until the New Year for the new letter to be issued, so that they could get a newer" car. This led to major peaks and troughs in sales over the year, and to help flatten this out somewhat the industry lobbied

It should be noted that there are no restrictions on using a vanity or cherished registration on a car that is newer than the original date of the registration plate, but it is prohibited to transfer a registration that is newer than the vehicle it is used on. This is to prevent the transfer of newer registrations to older vehicles as a measure to protect consumers.
