We (David and Peggy) are a couple of entrepreneurs who registered about 500 domains circa 1992 for a brighter future based upon “Unified Numbering”. It is a one number identification system designed to replace all of your addresses, phone numbers, account numbers and other identifiers of all kinds with one name or number of your choosing and one single password for absolutely everything you do over the course of your lifetime.
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 as of 2019. 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!)
Good luck in your acquisition and venture!
