Possibly very valuable - but - only to a very few people.
I'm sure if someone like Richard Desmond took a shine to it, he'd shell out low to mid £xxxxx for it, just for the publicity value. If you could get more than one interested party, who knows...
On the other hand, if no-one like that was interested, it would be one of those nice names that never goes anywhere.
Try Max Clifford too - he'll know if anyone in that industry is looking for publicity.
