Silly prices, but the rationale for putting on a higher price is that you can always come down, but never put the price up. eBay's a difficult one to suss psychologically. Do you just do a BIN at 15% over what you want, or do you put a higher price on it and make the buyer feel better for getting a discount. But then you find that some people won't make a best offer because they are afraid of paying more than they need to, or others will only ever make a derisory offer and presumably are happy with the occasional trophy, whilst most of the time the vendor recognises that valuations are poles apart and either declines or ignores the offer.
To go back to the original post, a 100% premium is not outrageous when compared to the typical offer at 50-60% of your asking price, irrespective of whether the BIN is a fair price or not. Make an offer at 50% of the listing price and see what happens, assuming that is reasonable.
