One thing I can say specifically about BINs is that, most of the time, the asking prices are too high, leading to a loss of interest by bidders. When I list notes with fair prices and below-book prices, I find my items tend to get overlooked because most people assume that the item is overpriced.
So true! And many sellers are also listing notes at a high starting bid which also turns off potential buyers. Fewer sellers seem to have enough confidence in the market to use low starting prices... However-- this is understandable as sellers do get turned off/ and there seems to be a slump.
BIN is not the enemy... "Best Offer" is
Well I think they're both problematic. Unfortunately there are a few unscrupulous sellers who are asking high BIN prices and astronomical Best OFFER ceiling prices (which a lot of people just don't get). I have bought a few items (only 1 time per seller) at high starting bids and have almost always been turned off as the notes have either been pressed or over-graded. I thought I was avoiding a bidding frenzy... but in the long run it wasn't worth it.
I, for one, used to watch eBay on a regular basis, and have had a hard time tuning into it at all lately. I might look at their listings a maximum of 1 X per week (as compared to everyday back in 2003/04).
Buyers are getting wary of poorly graded notes, not buying in person, TPG, and speculative US $ prices. Its pricey to list the items too. And then there's Paypal!
IMO: The above is not good for the market - nor the hobby. Now that the shows are so good, and there's so many better live auctions, I wonder how online auctions will do? IT seems as if there's a never-ending-supply of redundant common "filler" stuff, and only a few interesting desirable notes.
UPDATEApparently an HPA insert was sold on eBay for about $40 (condition unknown).
UNC notes of this insert have been selling between $500 - $600
Does that low winning bid imply there really are less people following eBay?
