This then begs the question, how are the dealers getting so many of the full error sheets. My best guess, is that a select few have inside tracks within USPS. Also they must barter heavily to get the material. There are 2-3 dealers on eBay
that have seemingly 75% of the error market cornered. The hobby has a lot of manipulation and
All the legit wheeling and dealing in the world won't land you the equivlant of Powerball odds hitting a 50-100 totally error sheet out of a few hundred million stamps offered. Yes naive people who come across stamps will let them go, but I suspect dealers have to acquire them from face up to 20% max SCV for there to be any room associated with the first rounds of markup. Then once the supply is generally shared, a valuation is assigned based on demand and quantity outstanding.
I wonder if you buy a PB error of a 1/50, essentially a 1 of a kind, and you set the price at $20k, will it essentially pin it to 5k as a going rate. Probably not because, it will be compared to an invert like cia/nyse and be pegged accordingly to a 25% of that. Its clearly not as desirable as an invert. So it's more like 5k PB with an ask of 1250. Me thinks it works something along these lines, where it's all scalable starting from the premium material prices on downward.
