.mobi l-ll.mobi???

[Oompa]

lnl.mobi

Would a lnl.mobi be good to register? And if so, how much could I look at selling it for?

Your title says L-LL rather than LNL ...

But either way the answer is the same. If it is something that is commonly known to an average person with a hyphen or as a mixed letter / number combination (and not a trademark) then you might do OK, but generally those are far above the tideline of what has already been taken. You want stuff that is better than much of what has been taken.
