Minted by the United States Mint. The coins are guaranteed by the U.S. government to contain the stated amount of actual gold weight in troy ounces.

The gold must by law come from sources in America.

The Gold Buffalo is the only American official legal tender gold coin in .9999 gold.

1 oz Gold Buffalos are legal tender with USD $50.

Each of these coins are graded as PF 70, which is the perfect score on the NGC scale to 70. The coins are graded by the Numismatic Guaranty Corporation (NGC), a world class third party coin grader. These coins are thus of very high quality. The coins are also "Early Release" editions. Under NGC regulations, that means that the coins have to be submitted for grading within 30 days of the coin being released. Collectors like "Early Release" coins because they leave the minting press first and are thus potentially of better quality compared to coins minted further down the line. 

The encapsulation ensures that the coin is well protected.
