Howsit!
Overbite.org is a nice medical term, I don't think to wait for buyers to come to you would work for this one, you might need to do some outbound. To companies with the keyword overbite in their domain name or website and possibly already a .org. I know many pediatric dental surgery non-profit type companies that would smile about this name (pun intended). $5K to the perfect buyer, $1K if you wanted to sell it quickly.
Booger.org is cool, would love to send some emails with that name. The .com is for sale for $9,999.. Woah that's kinda cheap. Well, booger.org would be 1/10 or 1/15th the value of the .com so perhaps around $1,000 - $2,000 USD.
