There is a massive gold prospector community in my country that sells gold nuggets on ebay.com.au
Someone purchases a gold nugget and puts the mailing address as my post office box and then receives bitcoins in return.
It seems that the nuggets can vary quite a lot in price.
$1,290 AUD for 31.1 g

How much BTC do you have to exchange for nuggets?
Also, have you thought of a website listing the reputable sellers you want to buy from (i.e. you know they are not selling fool’s gold) and the price/gram you want to pay so that scouts could make money buying these nuggets for you?
I have heard that the easier it is to participate in a transaction the more people will be attracted.
What do you think?
