I dont know if this is happened to any of you but I have noticed that what you pay for a Theo Wanne mouthpiece it seems to depreciate in value when you go to sell it even if its in like new condition you are lucky to get half the price you paid for it. Im surprised because these are really good and well known mouthpieces. The only thing I can think is there is too much choice and competition out there. Compare a Wanne mouthpiece to a vintage Lawton, Link or Guardala and these pieces seem to hold there value and even escalate in value. While the Wanne depriciates in value. Doesnt make sense.
