'W' if not used much in French. But it can stand for 'web' for example.
Anyway a LLL name in a major TLD is obviously worth more than reg fee.
I would appraise at low-$$$$.
I think the value of LLL names in the major TLDs will continue to increase over time. These names are a must-keep IMO.
There are better letters still available but they seems to have potential TM issues... your 3 letters are not bad, will worth a lot in few years. 3 letters in TLDs is a good and sure investment.
