Once a nugget reaches a couple of Grams in size, it can be made into jewelry, and is therefor worth more. Wire gold and other specimen gold pieces are much more valuable because they are so rare. So, when you are looking to buy a nugget at auction, don't be fooled by the tricks of the trade that some ripoff dealers use. You should count on getting a nugget at auction for less than you would pay for it if you were buying it direct. That is the whole idea behind buying at auction anyway.
Buyer beware, and happy hunting, even if it is cyber-prospecting.
Sold in an auction by an unsrupulous dealer, you may have been taken to the cleaners by bidding on what you thought was a bargain. Here's a reverse example. But, here is the truth of the matter. The bottle is not your standard one ouncer. Just to make my point about buying a piece of gold for it's character, look at this one.
