Coondog - I don't have any pics to post with this, but will try to answer your question the best I can.
If a person is digging \"wild\" ginseng from scattered patches in the woods. and is only digging legal (3prong plants in most states) plants without damaging the roots and handles and dries them properly (not broken or moldy or overly washed), then there should be no worries about having the price discounted.
If dug and handled as described above you will have different age class plants with different shapes and good wrinkle to them. Below I will list some undesirable things to watch out for as a buyer, and what a digger should expect to have his/her ginseng discounted for.
1. damaged roots (you can get away with a little, but expect to be discounted some if more than about 5-10% are damaged (broken or gouged) The higher percentage of damaged roots the more the price will be discounted. (You are going to have a lot of the very fine hair roots break off no matter how careful you are. This is not what I'm referring to.)
2. Moldy roots. These are pretty much worthless (would you buy moldy produce?)
3. Slick roots (If they don't have good growth rings, and are smooth and very light colored chances are that they are cultivated. You do find a few slick roots in the wild, but If there are a lot of them and they are big for their age then they look like cultivated roots which can be bought for a LOT LESS than wild roots).
4. Dense Heavy Roots. The buyers want light \"corky\" roots. I'm not sure why, other than what rootman had to say in his post about bonemeal and fertilizer being added to the soil.
5. Overly washed roots. Too much washing will give the skin of the root a lighter appearance colorwise. The buyers prefer a darker colored skin on the root. I've heard several ideas as to why this is, and am not sure that one of them is more correct than the others, but this is how it is. A seller should not expect to be discounted a lot, but may be discounted a little.
6. Poorly dried roots. This would include moldy roots, but even without mould if they are discolored on the inside then they have not been dried properly(or possibly stored for too long). A properly dried root should be a creamy white on the inside.
7. All younger plants of the same age class. (Once again this indicates that they are being grown (cultivated).
8. Small roots. A lot of times these are underage plants with only a few bud scars. Often times there may be a few mixed in, but as a buyer or seller if there are a lot then the price will drop (if you can find a dealer who will buy them) (If I notice a bunch of young roots I won't buy it.)
9. Long slender roots. I've heard a lot of reference to carrot like roots, but I think that a better description would be to say shaped like a curved pencil. The end buyers just prefer short fat shaped roots. If the majority of what you have look like this expect to be discounted some. I believe that this has more to do with regional growing conditions and is already reflected in regional prices though.
These are the top things off the top of my head. Hope this is helpful to new buyers or sellers. This is my first year buying, but I have picked the heads of several dealers over the years, and have met a few new guys this fall that have been very helpful.
There are some very good diggers on this site and most are doing a great job digging and handling their ginseng. Most everything I've ever seen on this site from the diggers is top notch ginseng and should expect to get top price for it. With that being said, I have to say that some of the general public is not nearly as good at taking care of there ginseng as I've had several people bring me some poorly handled roots. I've also turned away a couple with extremely small stuff.
I don't have any pics of the undesirables to share, but this pic of a root that I dug last fall has about everthing you are looking for. Good size with a long neck, good wrinkle and shape.
