Somebody can see it as brandable domain, so its value vary from person to person.
for some it is only a reg fee, but if it can attract some body than it might be low xxx, Good Luck though.
btw did you submit it to BB
It's not a terrible brandable, and if you owned one of only say a few thousand then you'd have a valuable name on your hands. But the market is full of such "brandables", and better ones which are more pronouncable too.
You can put it on a brand site like Brandbucket or the like, but from my knowledge sales are very rare (can take years or no sale).

There's no reason for anyone to search for "Feseb" as it has no meaning (hence it being a "brandable" where someone makes it into a brand).
As AuctionBio stated, value with brandables entirely depends on the buyer and their budget.
