I owned this domain for several years, never received a single offer for it or someone asking price for it, in fact I kept it registered that long just because I always had the idea of develop it but never found time to do it so I recently decided to let it drop.
It is true I never bother to seek for a potential buyer, never did outbound marketing for this domain, so maybe you can find the right buyer if you are lucky.
Based on my experience with the domain, if you just plan to keep it and wait for the buyer to come to you, it is worth reg fee, but if you do outbound marketing and you find the right buyer, maybe you can get low xxx for it.
