domain Mothering(.io) and Fathering(.io) Appraisal

I would say $1500 each

I'd say they're worthless or close to worthless.

io requires that the word to the left of the dot be something to do with tech, or be an open vessel kind of name. mother.io and father.io would be those kinds of names. But mothering and fathering kind of pigeonholes them into something to do with parenting, which doesn't really go with .io.

I'd be shocked if you sold them.

Reg fee. As above.
