For sale: H6RBE cherished personal vehicle registration

Sold to venture capitalist Spencer Day, at auction in Whittlebury Hall, Northamptonshire in January 2009. Confident of a good return Mr Day bought this cherished plate as an investment.

Originally issued to George Drinkwater of Braddan for his steam powered car, this, the first registration number issued in the Isle of Man in 1906, was sold at auction to an undisclosed bidder in February 2009.

Sold to Mr Singh! Given the sale price of older brother S1 NGH and the popularity of these personal numberplates in the Asian community, MR51 NGH secured a lot less than expected for the Treasury.

Fit for the Queen and the subject of media attention, this royal mark was secured by a Berkshire-based businessman, at auction. He said he was "determined to keep it in British hands".

In addition to the rarity, the huge appeal for this cherished plate may come from the fact it resembles ‘GB’, short for Great Britain. It was just one of the prestigious vehicle registrations snapped up at a DVLA auction in Wansford, Cambridgeshire, September 2008.

The second of the DVLA’s single digit O-series was auctioned at Ardencote Manor, Warwickshire, in March 2009. The rest are set to follow at subsequent auctions.

Once owned by the Essex County Council, this registration mark was sold at Bonhams auction in 2005, clearly breaking its anticipated sale price of £30,000 to £40,000. The winning bidder was an unnamed telephone buyer.

The private plate with a very desirable combination set the record for the highest price paid for a private plate on eBay, in 2007. The increasingly used term Chief Executive Officer, no doubt fuelled the appeal, which would have had many business and corporate executives fight for the right to the ultimate status numberplate for the city.

The younger mirror image of the legendary A 1 numberplate went under the hammer at an early DVLA auction in 1989. Apparently, nearly ten years later, both reg numbers were sold to the controversial Prince Jeffry of Brunei, brother of The Sultan of Brunei. Both numberplates were registered to identical white Bentley’s ready to collect the Prince and co from his private jet.

With this great plate, perhaps the DVLA were commemorating the 100th anniversary of their personalised registrations auctions in April 2006. Whether your nickname is “Loo” or not, ‘I OO’ would add a nice touch to any prestige car.

Just a line and a circle, this rarest of dateless numberplates demonstrates that less is more. The minimalist private reg, never released before, was sold at a DVLA auction in Whittlebury Hall hotel in Northamptonshire to a private buyer. It was the first release of the 'O' series.

Surely the "royal with ease" of all registration plates, this was sold in 1993. It is alleged that this sale marked the beginning of an explosion in the market for personalised numberplates. An anonymous bidder, possibly an Arab Sultan, secured the regal crown.

This cherished plate went under the hammer for 30 times its reserve at a DVLA auction in South Yorkshire, November 2008. Exceeding his planned budget, winning bidder businessman Robert Harverson said after, “in the end, I was just determined to buy 1 RH and nothing was going to stop me”.

Despite being technically less of a match to the popular Asian name Singh, this dateless mark fetched over two and a half times the price of S1 NGH, its younger brother. It’s hard evidence and hard to believe that the year of issue can make such a difference. Sold in 2006 to a Sikh, this cherished plate had previously generated a lot of interest since Singh is a popular name in the Sikh community. 51 NGH is the most expensive Asian numberplate sold in the UK.

The estimated auction price for this registration plate was about one third of the hammer price. It was auctioned off in July 2005 in Perth, Scotland and was originally registered in January 1928 by Perth County Council.

This plate was once placed on the Pope John Paul II's car for his papal visit to Ireland. Bought in 2006 by the Chelsea boss Roman Abramovich, this "very important" cherished numberplate was bought with the billionaire tycoon’s pocket change for £285,000.

This private plate was sold at auction in Chichester, in 2006. It was the first registration number to be issued in Cheshire at the beginning of the last century. Bought by Mike McCoomb, who had previously sold his mobile phones business to BT for around £40 million. Apparently Mike bought this numberplate for his son, who at the time was under ten!

This registration was sold in March 2009 at a DVLA auction in Warwickshire to Nabil Bishara, a Lebanese property developer. The record auction reserve price of £20,000 echoed its desirability. Nabil bought this highly sought after private plate for his wife’s birthday - lucky lady!

S1 may have been Scotland's first ever numberplate. It was certainly Edinburgh's first vehicle registration. It was bought by anonymous bidder at Bonhams in Chichester, in September 2008. The winning bidder claimed the cherished plate would be displayed on an old red Skoda!

Number ONE! The highest price for a British vehicle registration number happened at a DVLA auction in Jan 2008 when businessman Afzal Khan paid £440,625 for the Formula One initials. He bought it for his Mercedes-Benz McLaren, which cost £200,000 less than the numberplate.
