On what basis? If you are lucky, and i mean lucky, you may find somebody willing to go that high, but only an end user. To a reseller you have a $1xx name unless it receives traffic, which would obviously add value. I own many 3 character domains and have waited a while for that sort of offer to come through!
Feel free to list it on my site for sale www.3characterdomain.com - it won't cost you anything.
p.s. If you have it parked, I would use keywords relating to mobile phones, as panasonic have a model out called the x77.
About $150-200 right away to a reseller.. EU can be anything, but it's hard to find EU's with 3 character domains, 3 letter although is a different story.
