Ditto on the #9 on Ebay. Been watching them go for about a year or more and they have all pretty much sold around that price, 300-500 depending on condition and if the cast trivet was there. Sometimes higher depending on the buyer and last second bidder wars. I believe I recall one or two going for 600 plus on occasion, seem to remember one in the 700's with a trivet that was pristine.
I'd definitely put at least a $300 reserve or starting bid on it if there's no pitting, etc, etc. More if selling with the cast trivet.
I would definitely not pitch the wire trivet. Not worth much, but useful for other purposes. If you really don't want it let me know? I'd use it for baking and it would be cool to have it as a conversation item. Let me know what you want. The wire trivets were sold/used more for the aluminum roasters of the 50's. See the RB page 150.
