It's probably because most of the trade made by the user "the joint" were done before the Trust system was introduced.
Anyway I said that they go for less because I've been selling them for less .. in this period I've seen that the price range between 1.1-1.4 for 2013 brass
To some extent, yes, many trades were made before the trust system was implemented, but I've also had several successful, recent trades that aren't reflected in my trust rating. I just haven't been diligent about requesting that the buyers leave feedback.
That upper end of the range you stated sounds realistic. I'm sure deals have been made at 1.1 BTC, though I'm not prepared to sell at that price, especially for coins that are in such good condition as these.
