Instructions
Identify the current spot price of gold. The spot price of gold is the price of gold per ounce traded on either the London or New York bullion markets. The price is available online, in real time, on any website that lists commodity prices and on all major news sites. An American buffalo bullion gold coin has one ounce of gold.
Locate the American buffalo coins from 2006. These are are no longer available from the United States Mint, so they need to be acquired on the secondary market. They are widely available, however. Check out online auctions to get a sense of what current prices are, as they sell for a premium over the gold price. Look at past sales and make sure that you are buying the proof rather than uncirculated version. Uncirculated coins are the general production coins. Proof coins are special coins produced for collectors. Proof coins have frosted devices (for example, the Indian on the obverse) and mirrored fields (on the background).
Buy your coins. Armed with the current spot price and aware of the online market, you can go to a local coin shop to try to see if you can negotiate a better deal.
