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.

The UK’s most expensive number plate to date is the F1 registration number purchased by a British businessman for £440,625 in 2008, though that’s just small change compared to the £7m spent by Abu Dhabi-based Saeed Khouri on the 1 number plate – officially the largest sum of money ever spent on a registration number.

Even in the early days, people recognised the significance and enjoyment brought by owning a prestigious or personalised number plate and often kept them within the family for many years. Their significance is often highly personalised to their owners. Some like to have a registration that originated in their local area, some are attracted to owning their own initials and others enjoy the fun of a word based registration mark.

It had been expected to sell for between £15,000 and £25,000 but the first Manx vehicle registration plate ever to be issued was eventually sold last week for £100,000. It is, says auctioneer Murray Keefe, a valuable piece of Manx history.

“It was the first Isle of Man number plate and people do like to have number 1. At the auction we had 4 telephone lines wanting to bid on the number plate and quite a few bidding in the room so I was not surprised it made so much money knowing that some of the plates in the United Kingdom make substantially more than that.
