Jean is just about the most common male name in French if not the most common, so potential is big. Jean is also a woman's name in English but far less common. I'd say expect $,$$$, possibly in the middle. Ask for $10K if you want but not more, and don't restrict bids or offers to be only above $5K. See if you get any. We've all heard the rule of thumb the .net version of a domain should sell for 10% of the .com, and it's not that far off in fact. But if you focus on it being the most common male name in French you got a big pool of buyers. Domainers will offer less than $5K of course, but you want an end user for this one. And I even bet some male domainers on DNF have Jean as their 1st name if they're francophones lol. Pay attention to your listing on Sedo, they have rich international buyers who may want it. All n all, good pick you made, good luck
