This Salem Witch thimble recently sold on eBay for $384.79. There were sixteen bids from nine different bidders, four within the last eighteen seconds of the auction. I don't know what the seller's minimum starting bid was, but the first bid referenced is for $13.00.
I mentioned this thimble in my little tirade about the price a "Stitch in Time" thimble got a while back. If I find a relatively cheap one, I might get one, but I'd need a lot more money and a lot fewer relatives to dish out anything close to $384.79 for one.
