You've got one "brandable" and two "enthusiast"/"community" domains. These require development and marketing because of the (likely) lack of type-in traffic. I'd say regfee. Backlinks, if any, would help...
I'll give you $11 Canadian for expertfishing.com. Not even joking.
Honestly though its hard to determine a price for them considering they are only aged and have nothing else going for them well other then a bit of brandability but I doubt they get much type in traffic you'd have to toss up some stats to see but your better off developing them thats unless you really want to sell me expertfishing.com for $11 bucks hahaha.
