I can only tell you what I do. I take a bucket from the best area I can find and use fines and small pickers to salt bags of paydirt for sale and gifts and I do this for two reasons.....
1. It makes me a little extra cash, more than what the gold would be worth in the first place, not much but more. I give some away to kids too, show them how to pan it. No amount of money can match the look on a kids face when he sees gold in the pan! Its pretty freakin awesome.
2. Besides the extra cash if you do it right and generously salt the bags and DONT GO THROUGH THE DIRT YOU SALT there is a good chance you are doing another miner a big favor. A lot of the dudes that buy paydirt online do so because they physically cant get out and do the mining anymore. Old timers and disabled folks. If you do it right, not only do they have the chance of finding a nice picker in the dirt you sent they are guaranteed a decent amount of gold in the bag. Folks really appreciate that. A little coin in your pocket and a good deed to fellow miners. Win win if you ask me.
