PCGS PR-70 Gold Buffalos (Black Diamond)

The 1 oz Proof Gold Buffalo PR-70 PCGS (Black Diamond) coin comes from the United States Mint’s Gold Buffalo series. The Gold Buffalo, introduced in 2006, was the first Gold coin with .9999 fine purity from the U.S. Mint and features a denomination of $50 USD. The Black Diamond collection features a limited-edition label, instantly adding to their value over time due to low populations. Many Gold coin series have mintages into the hundreds of thousands, but this 1 oz Proof Gold Buffalo Black Diamond coin graded by the Professional Coin Grading Service (PCGS) has a lower population creating a higher potential return on your investment in the future. With this exclusive limited-edition label, the final populations are very low and highly sought after.

Investor Advantages:

  • The Black Diamond label is only available from PCGS and is an APMEXclusive®.
  • Proof coins are treated with a special minting process so the softly frosted, yet detailed images seem to float above a mirrorlike field.
  • PCGS has certified these coins as flawless, even under magnification, giving them the ultimate grade of PR-70.
  • In 2016, of a total mintage of 21,878 1 oz Proof Gold Buffalo coins, PCGS has just 449 listed as a perfect PR-70 with the Black Diamond label.

Enjoy Sustained Value From Gold Buffalo Coins

The history of the American Buffalo Gold coin began when famed American sculptor James Earle Fraser created the 1913 Buffalo Nickel, which paired a Native American chief in profile on the obverse and a buffalo on the reverse. These American icons have appeared throughout history in art as well as on coins. Today's Gold Buffalo sustains that tradition, though the United States Mint only began producing these Gold coins in 2006. The original Buffalo coins were discontinued in 1938, but this impressive reappearance allows investors to once again appreciate Fraser's unique design, now in .9999 fine Gold. Don't let the opportunity to add these coins to your portfolio slip through your fingers.

Investors can gain tremendous value from the PCGS PR-70 FS Gold Buffalo featuring an APMEXclusive® Black Diamond label. Each coin contains an impressive 1 oz of .9999 fine Gold. Its perfect PR-70 condition makes it a high-value choice for those who want to generate a high return on investment.

These Proof Gold Buffalos have no defects or flaws to minimize their beauty, and the Gold Buffalo retains its beautiful luster thanks to sealed encapsulation from PCGS. This exceptional coin serves as the perfect addition to anyone's portfolio of Gold Buffalos. The finely reeded edge and detailed engraving make this Gold Buffalo beautiful as well as valuable. Indeed, American Buffalo Gold coins have historically retained their value long after minting.

PCGS, one of the nation's premier Gold grading services, has guaranteed these Gold Buffalo coins have retained their perfect PR-70 condition, which adds to their appeal. You will also appreciate the APMEXclusive® Black Diamond label. It references a buffalo named Black Diamond, who resided at New York City's Central Park Zoo in 1913. Legend has it that James Earle Fraser used Black Diamond as his inspiration for the first Buffalo Nickel coin.

Rare coins carry an additional premium representing numismatic value, which is based on scarcity, quality, demand and intangible factors.

Coin Premium Appreciation

Over time (usually at least 3-5 years after release), the premium of a particular coin may increase due to limited availability or other factors such as demand and quality of the coin.

Introductory Premium

Current Premium

The premium or additional cost of a bullion coin above and beyond the metal value of the Precious Metal it contains.

Grading and Warranties

Our company uses the numerical Mint State (MS) grading system, which rates uncirculated coins from MS-60 to MS-70.

Typically, the higher the grade, the better the quality of the coin and in turn, the higher the value. The grade assigned to a coin reflects its strike, luster, marks, scratches and overall eye appeal. Grading is a subjective art and depends on the opinion of the person grading the coin or currency. Thus, grading can and does vary from numismatic coin firm to numismatic coin firm, from grading service to grading service, and from expert to expert. A difference of one grade (e.g., MS-64 to MS-65) can result in a significant change in the valuation of a numismatic coin or currency. Grades and descriptions of numismatic coins and currency are opinions, not statements of fact or guarantees, and are based on standards and interpretations in place at the time of grading.

When you acquire a coin or currency from APMEX that is independently graded by a third-party grading service such as Professional Coin Grading Service (PCGS) or Numismatic Guaranty Corporation (NGC), APMEX relies entirely on the expertise/determination of the grading service. In addition, we rely upon definitions provided by these independent grading services, including definitions of such terms as PCGS' "First Strike®" which refers to coins packaged and delivered by the U.S. Mint in the thirty (30)-day period following the initial sales date of a new product. We do not re-grade or independently evaluate the product's grade in its sealed holder. APMEX reserves the right to deliver independently graded coins that have been graded by an independent grading service of APMEX's choice such as PCGS or NGC. APMEX guarantees that the numismatic coins and Precious Metals it sells are genuine. APMEX expressly disclaims any other warranties with respect to coins or Precious Metals, express or implied, including the implied warranties of merchantability and fitness for a particular purpose. See our User Agreement for a full disclaimer of warranties.

Premium Appreciation

You should know that different market factors may influence the price of a specific Precious Metal or the associated premium. For example, the price of a numismatic coin may be affected by such factors as grade, scarcity and marketplace demand, while the price of a bullion coin is closely tied to the spot price for the metal content of the coin as well as year-specific mintages. Past performance and growth projections for one type of Precious Metal may not apply to other types of Precious Metals that APMEX may offer.

Holding Period

Our experience suggests coins of specific quality or scarcity that have demonstrated historical premium appreciation tend to do so at least 3 to 5 years after the coin was produced. Market conditions and other factors will always impact the future value for coins, and therefore premium appreciation should never be considered to be guaranteed.

Our Prices

Our prices are set internally based upon our analysis of a variety of factors and are not necessarily tied to the prices quoted by any other organization. Prices are subject to change based on market conditions.
  APMEX acts as a dealer and generally owns the Precious Metals it buys and sells.


All investments involve risk and Precious Metals are no exception. The Precious Metals market is speculative, unregulated and volatile, and prices for these items may rise or fall over time.

APMEX generally classifies coins as bullion, semi-numismatic and numismatic. Some coins may fall within more than one category, depending on their specific grade or condition. Other dealers and organizations may define these terms or classify these coins differently.

Precious Metals generally have a premium above their melt value. Premiums may increase or decrease based upon current market conditions such as supply and demand. Changes in premiums may affect a Precious Metal’s pricing beyond changes in spot prices.

Precious Metals can go down as well as up in value. These items may not be suitable for everyone. APMEX does not determine the suitability of any specific person to purchase Precious Metals. You should consult with your independent financial advisor regarding whether such an investment is right for you. You should not acquire any products from APMEX if you are not competent or qualified to make your own financial decisions. You should obtain a thorough understanding of the Precious Metals products before you acquire these products as a collector or investor.

The investment value of Precious Metals depends in large part on the price you pay. If you are acquiring any of APMEX's products as an investment, you should evaluate its current market value, potential for appreciation and liquidity, and consult independent sources regarding these factors. APMEX does not guarantee that any client will be able to sell Precious Metals at the original purchase price or a higher price in the future.

APMEX is not responsible for any changes in tax laws or other statutes which may affect any profit or salability of your coins or currency.
