How much should a #1 collector's edition Archie Digest Library Betty and Veronica Double Digest Mag. start at?

I have an Archie Digest Library Betty and Veronica Double Digest Magazine No. 1 Collector's edition. The front and back cover aren't perfect, but in its entirety it is in very good condition for being made in the mid 80s. So I would like to know how much I should start a bid off at or start one at all.
