Sell them to whom? If to a domainer, then to whom should he sell them?
Suppose someone wants to build a site on one of these domains. OK. They have a million other domain options that are exactly as relevant / irrelevant as this one. Since they have a million other equally good options, why would they pay extra for one of these?
If those questions are hard to answer, then that probably means these domains are hard to sell.
Near zero value, as far as I can see.
