Well, honestly, my first thought is that those dealers really don't know the difference and may well be cheating themselves. The wild market is moving to quality over quantity. Not all ginseng is created the same and as Strong Prong pointed out...it does not all have the same value.
If I could give you all one wee bit of advice...get yourself a couple of those one dollar plastic shoe boxes at walmart to put your ginseng in after it has dried. Once it is dry, it will keep just fine in the plastic box with the lid on. And, you will not be breaking the ginseng up by moving it around in a paper or plastic bag. Every time you pick up a paper or plastic bag with ginseng in it, the bag closes up around the bottom corners and breaks off the finer parts of the roots.
Which leads me to another point. Lets say I buy 10 pounds at $1000/lb. We all know there will be fines (broken off small roots) in that 10 pounds. Most normally, we can assume about 7% is going to be fines. That means I just paid $700 for the fines in that 10 lb lot. The problem is, the last fines I sold, only brought $32/lb (that is no typo...32 bucks per pound). So, we have .7 lb that cost us $700 but is only worth $22.40. That means the remaining $677.60 is added to the cost of the remander of the lot, or 93% which is 9.3 pounds in this example. If we divide the $677.60 by 9.3 pounds that adds $72.86/lb. So, In this 10 pound example at $1000/lb, we actually are paying $1072.86 for each pound.
Let me ask you, would you go to a different dealer if he or she were willing to pay you $72 more per pound??
