Four Letter .com domains that start with K or W

[mpsarouthakis]

I have about 900 four letter .com domains that all start with the letters K or W. Registered in 2007 before the sell out in November 2007, my thinking was TV and Radio stations in the US must have a call sign that starts with K (west of the Mississippi) or W (East of the Mississippi) and I would be able to sell a few each year for $xxxx to new stations, that would more then offset the annual renewal fees. The reality is I have sold 16 for as high as $250 on SEDO and about 50 on eBay for prices ranging from $14 to $75. Traffic is consistant but not heavy and generates very little in click revs.

My question is should I try and find a buyer for the entire portfolio and if so what do you think it is worth and where is the best place to sell/auction an entire group of domains like this?

Thanks in advance.
