For poker-pla.net I'd say low-mid $xx unless you develop it a little. The hyphen doesn't help but I do like the idea behind it and I'm sure to the right end user it could be worth a lot more.
Since you have those other pla-.net names it might work better if you made a themed logo like you have with poker-pla.net ... make them all similar and sell them off (even appraise them) as a network of sites? I don't know, just a suggestion... it might help increase the value.
