The key here is the statement made above ----"The low values", There is a flood on the market right now of "low values" and all the recent MNH sets that are being put out by the various postal organisations .There is no interest to buy this material at anything but 2 or 3 cents apiece . The good complete sets of the early British Colonies still get decent prices at auction.
What is gone are the days when you could go to the major stamp auction firms and buy bulk collections at a price of 1/2 cent to 3 cents per stamp and then list a stock sheet for 8 or 10 cents per stamp on
ebay and get it .Now your buying at 3 cents per stamp and getting 4 cents per stamp and loseing the profit for being a reseller on
ebay.
