Re: Selling another artist's art
I would first contact the most prestigious gallery in your area to see if they are interested in consigning it for a short time, something like 90 days. Expect to pay 40% or more commission. Price it at retail value and give the gallery owner the maximum discount you would allow them take.
Or, contact a large reputable auction house that handles lots of sculpture. You will probably have to ship it to them. Personally I would not put something that valuable up for auction without a minimum starting bid that I was comfortable with. If nobody is interested in at the moment, it could sell for a lot less than it might later when there were more interested buyers looking. From what I read, many auction houses charge the seller nothing, but hit the buyer with a "buyer's Premium" that runs from 20%-30%. Regardless of who pays the fee, it is going to reduce what you end up getting from the sale since they buyers are not going to bid more than 70%-80% of what they perceive the piece is worth to them.
