I think you could raise quite a bit of money with an auction. Just make sure that the auction runs for a period of time to allow it to be marketed. If you are going through a charitable group, have pictures of the basket distributed to all members so that they can show the pictures and sell tickets to a wider audience.
Can't believe that this is only your second basket. Fabulous.
P.S. I would love to purchase tickets for an auction for this item. Please PM me if you do plan to auction it.
