There are several members here who use the free posts on ebay to place things for sale at the, " I do not care if I sell this, but if you are going to pay that price number " then they just let it ride. Sometimes the market catches up and they get their asking price, sometimes the book blows up and they sell it, other times it just sits and sits. Only one way to really tell as this current market has been crazy.
You never know , one of those GME or Crpto millionaires might see those and know how hard they are to come by and not really care about price.
