I hear what you're saying pinsanity - you make some good points.
One of his points he is making (for those of you who don't get it) is that the current market has been/is sustained by the fact that we collectors can get almost all our investments back when we sell. A market like this can withstand (and this is why we have seen) rapid price increases. In other words, if you buy a pin for $10,000 say and can sell it for $9,000 6mo later say then all that is lost is $1000 (& some potential investment gains say). If the initial price was $5000 and 6mo later you sell for $4000, it's about the same loss. If you have to sell your $10,000 pin for $5,000 then this is a whole other story and this can have a tremendous impact on whether or not people buy NIB.
