^ Wow, $14 million for the number "1"? Good grief!
Mine's not a vanity tag, but it's a "Pet Friendly Tag" issued by the state of Maryland. It has the word "PET XXXX" (my tag number) and at the bottom it says "Spay and Neuter" and there's a picture of a dog and cat.
I especially love it b/c I've it so long now it's been transferred to my third car! And the number is really low as I got one of the first ones.
