I would never do this, it is a distress tactic that unless you get lucky, will result in a below market price. Any small volume collectible needs time to reach an adequate number of buyers. I have taken 3-12 months to sell specialty items, and the price is always better when you find the right buyer.
A fair price is when an educated buyer finds a knowledgeable seller. Simply lowering the price until you find a
willing buyer is not the same. There is a price at which someone will buy it knowing they can resell it for a profit, and they will buy quickly at that price.

and maybe you dont need the $, but some others do.....everyone is not you.
