For the .de domains:
Doesnt.de is useless. I really don't see a value in it.
oldest.de might have some value for antique dealers, but they won't usually pay much money for domain names. And even if, then they would rather prefer a German name, because English words a rather used for new, stylish things, and not for antiques. Even "omas-antiquitaetenstuebchen.de" would fit better. And to the worst, there is not even one noted sale of "oldest" in neither extension. So; I'm not very optimistic for this name.
