That is because you are not selling on ebay.
I have seen a seller on ebay, sell the same HL week after week for a ridiculous high price(Old Point Loma for $200). Finally someone comes by and buys it. The Forum is a buying/selling/trading place for serious and mostly professional HL collectors. Ebay is a selling place to all types of people, Collectors, novice and impulse buyers. You did the right thing and did your initial selling on the Forum, but I think you have to bite the bullet and sell where all the people are.
