Excellent potential End user "leads" here provided by RJ! In this context, at this time, I would venture $175 - $225+, IMHO.
Much less at the wholesale level. How effectively you market this domain to this former group of potential "leads" will dictate.
Also, I think the value could grow over time, as well ... as I believe with most ".US" domain names.
Best of Luck.
Nice premeire .us name brooklyn. Worth marketing too end users for sure. Many .COM florists LACK a quality prefix.. and your .us is a name they would consider in my opinion.
