domain StJohnsRiver.com lot appraisal please!

[dobermanDomain]

I am letting go of my StJohnsRiver domains. I would like to sell them as a lot, but may just put them up individually. My problem is that I have no idea how much they are even worth. Any thoughts?

STJOHNSRIVER.COM
STJOHNSRIVER.NET
STJOHNSRIVER.ORG
STJOHNSRIVER.BIZ
STJOHNSRIVER.US
STJOHNSRIVER.CO

Thanks! Any information would be greatly appreciated!

I am not sure about the commercial usage but for this name, I think someone can pay high $$$ for this name given that it is an exact match of the place and there might be commercial activity around it.
However, since I do not know the place/region, get another opinion on this name.
