Most expensive number plate in the world

A vanity plate was auctioned off in the United Arab Emirates to Saeed Khouri for a cool Dirham AED 52,200,000, which is equal to 9,254,948 Euros or 14,223,000 U.S Dollars or 71,11,50,000 INR.
Care to guess what it said?
"1"
That's it. "1".

The successful bidder said he bought it because he "wants to be the best in the world". Saeed Khouri, a member of a wealthy Abu Dhabi family, added: "I bought it because it's the best number." However, he would not say which of his many cars would carry the record-breaking single-digit plate. The oil-rich UAE began auctioning off so-called vanity licence plates last May. Proceeds from the auctions go to a rehabilitation centre for victims of traffic accidents.
On Saturday, 90 licence plates were auctioned off, raising a total of £12m.
The previous five such events raised more than £25m. It was auctioned for charity in the United Arab Emirates, beating the previous record of £3.5m for a plate featuring the number 5.
