Gave me a laugh. I think maybe the seller is having a joke.
I dont think it is the world's highest denomination. There was a Hungarian inflation note from 1946 which was 1 followed by 20 zeroes. Have one at home but I am away for a while, otherwise I would give you a picture. This was I think the highest circulated. The Hungarians did print the next note up, but did not issue it. See wikipedia and look for banknotes of the Hungarian pengo.
The Hungarian note does not actually have all the zeroes printed on it, so this could be the note with the most zeroes.
