We rarely notice car license plates. Maybe we should because some are valuable. A license plate just sold for $15 million in Dubai. It had the letter and number P7 on it. It is the world's most expensive plate. The previous record was also set in Dubai. In 2008, someone paid $14.3 million for the number "one" plate. No one knows who broke the new record. It will be difficult for the person's identity to stay a secret. Dubai's drivers will be looking for the P7 plate.

The money from the sale will help poor people. It will go to the One Billion Meals charity. This was started by Dubai's ruler. It helps to feed hungry people worldwide. The auction house said it was happy with the sale. It said: "We are proud to announce that the…charity auction…has set a new world record. We are thrilled that the [money] will go…towards supporting the…campaign, which aims to establish the largest Ramadan sustainable food aid fund."
