What is the best and most valuable domain name you have, as far as the name value is concerned? Did you create and register it yourself, or did you purchase it from another registrant?
I think if that was me - I would have said she can have it for $3000. I would assume she would pay it since legal fees would have been a lot more than $3000 to take you to court over it but IANAL.
I have a domain that Microsoft has been trying to acquire from me for about 3 months now... been haggling on price. Hopefully I can make some nice coin on it.
I owned flowbots.com several years back, picked it up as a drop because it was a PR3. Sold it right around the time the "No Handlebars" was huge.

Sadly I didn't realize what I had till I was already locked into escrow - effing GAVE it way for low $XXX, still kicking myself to this day.
