If you do a search online you could possibly change your mind. I saw one the other day that was around $7000.00 & a bunch in the $4000.00 to $5000.00 range. As you know it all depends on the individual item.
Ebay is offering free listings for a time.
If you do not want to sell it, start it a $1.00 with a really high reserve ($7000.00).
The bidding will give you an indication of its value. Heck you may end up selling it though.
