We (David and Peggy) are a couple of entrepreneurs who registered about 500 domains circa 1992.
We don’t want to be scrooges with these domains. Even though we have good uses planned for each and every one of them, we know that others might too. If that’s you, let us know. We’ll try to work with you the best we can.
That said, these are valuable assets which have annual registration fees we’ve incurred for all these years totaling around $750 each. So, $750 U.S. is the starting point for even the least valuable domains. (Unless we really like you and/or your use and want to help which we may very well do!)
Good luck in your acquisition and venture!
