I investigated the person the email came from a bit, and it seems they may be a domain investment company...I don't want to scare the off by asking too high a price, but I don't want to sell too low. I have a feeling they want the name in order to make an offering to the county, for which they are building a website for...or they have possibly already received an offer from them.
I would still price it as if the county people were interested in it, no matter who is really interested. Obviously, those county people are doing someting with their biz site, so you should assume that they would also be interested in dot com version.
Anyway, generally speaking (and that goes for any e-mail inquiry you get) don't be the one who mentions any price first, unless you are absolutely sure you would want to sell it for that. Simply, tell them that the domain is not for sale, but that you might consider an offer if its priced right. And go from there. If they lowball you an offer, be polite and say "No thanks." As long as they keep lowballing you, don't feel a need to counteroffer with any number. Usually, that means they are probbing you to get a feel of your range, or that they are not serious about it. So, don't give them the pleasure of revealing your target price unless they offer you a firm and fair/reasonable offer. If they offer you a serious fair/reasonable offer, you can either accept it (if you like it) or you can ask for somewhat more. If you're asking for more, don't sound rudeby asking for more just for sake of being greedy, write them maybe a sentence or two explaining why you are asking for more. But, don't start with "I just feel this name is worth more..."...
It's much better to say something along the lines of:
"This domain has a personal meaning and value to me, and I will not consider selling it until I am absolutely sure that the price offered is the one that will make me want to depart with it. Therefore, I would only consider selling it if you add xxx amount to your offer."
Obviously, that's just an example, which you can customize according to your feelings and needs, or to reflect your particular situation etc...
Anyway, always remember that you're the one who's calling shots, especially with the name that you know is/might be valuable (to someone.)
