Thankyou for pointing that out
It does not mean they are worthless
You should take a long look at the appraisals section, we get new members coming on here most days with similar names, some worse than yours, some slightly better.
Have a good look around the sale sections to get an idea what is worth what, what's selling and what's not, there are much better domains than your posted in the bargain basement section every day.
Why do you think they are worth something, what was your reason for registering them? I'm only asking as you consider yourself an expert on these things, so, it would be good to get an idea of why you registered them, and what sort of plans for sites you think could go on them to monetise them, things that would make them worth something.
What makes pley.co.uk worth something?
What makes valoan.co.uk worth something?
What makes moonwalks.co.uk worth something?
As far as I can see, pley doesn't mean anything, so it'll have to be an acronym for something, the thing with acronyms is, you can't sell them as a certain acronym, the buyer is the one who dictates what the letters will stand for, unless it's already a common acronym that could be readily monetised.
Pley it isn't even a word, all the dictionary sites I tried say "word not found". There are random 4 letter domain name dropping all the time, there are many others sitting there having never been registered, what makes your domain in some way valuable?
What about va loan, all I can see for that is this, "
A VA loan is a mortgage loan in the United States guaranteed by the U.S. Department of Veterans Affairs (VA). The loan may be issued by qualified lenders.". Which will be of zero use on a .co.uk, and as such, not worth anything.
Of course, valoan could be turned in to a brand, but anyone starting a new brand could use any old name and get the same effect, baloan.co.uk and baloans.co.uk are both available to register and would do the job just as well as your valoan.co.uk
As far as I know, there are no affiliate programs for moon walks, so it's unlikely that you'll make any money from monetising it, maybe if you hold on to it for many, many moons, they might do something like that one day, but I doubt there'll be an affiliate program for it. The only other option I can think of to monetise it would be a site about previous moon walks, which are very few and already well documented.
