Here it is on the AD site -
https://www.antennasdirect.com/store...v-Antenna.html - that's the retail price.
It's a nice antenna, but an older design. For used in perfect condition, half-new seems about right, so I'd price it initially at $50. There is a newer DB8e that is more sensitive. In 2009 (?) the FCC narrowed the part of the spectrum for TV, eliminating real channels 52-69. So any antenna designed for 14-69 has a wider bandwidth than needed, and is less sensitive than it might be without 52-69. And the DB8e has panels you can aim separately for wider coverage (at the cost of some sensitivity).
