Transforming raw gold into exceptionally crafted bullion coins requires a delicate balance of precision and craftsmanship. Essential for investors and collectors alike, understanding the minting process reveals valuable insights into the coin’s quality and purity. Follow along as we explore how the U.S. Mints masterfully produces one of the world’s most highly coveted coins, the Gold Canadian Maple Leaf.
The Royal Canadian Mint takes pride in sourcing gold from several diverse resources throughout North America. To ensure the best possible quality, sources may include mines, jewelry manufacturers, scrap dealers, pawn shops, and high-grade industrial scrap dealers.*
After acquiring the raw material, the next step is to refine the metal into exceptionally fine gold, a process the Royal Canadian Mint has mastered. As a matter of fact, the RCM houses one of the most technologically advanced refineries in the world and has steadily progressed year after year since creating the inaugural .999 gold Canadian Maple Leaf. The refinery at the Royal Canadian Mint was the first to achieve a remarkable .99999 purity solidifying its position as a global industry leader. Today, the RCM is the only refinery entrusted with issuing gold bullion investment products at that level of purity.
Various methodologies have been used to refine gold, however, the Royal Canadian Mint generally employs a complicated combination of pyrometallurgical chlorination and electrolysis.
As defined by the experts at ScienceDirect, “pyrometallurgy is a method of smelting the target metal by subjecting the ore or concentrate to a suite of complex physical processes and chemical reactions under high-temperature conditions, ultimately separating the metal(s) from impurities.” Together with electrolysis, this innovative process ensures the highest possible quality and exceptional purity necessary to create a .9999 pure gold Canadian Maple Leaf coin.
Step 1 The raw material is melted at an extremely high temperature and shaped into ingots to be tested for impurities.
Did You Know? Gold’s melting point is a scorching 1948° F!
Step 2: Because raw gold sources can contain anywhere from 10% to 70% other metal, often silver, the molten gold is then injected with chlorine gas to separate the impurities from the gold. The chlorine exposure causes the other metals to rise to the surface where they can be easily skimmed off. After this step, the resulting gold is .995 fine.
Step 3: To further refine the gold, it is cast in small, flat bars in preparation for electrolysis, a time-consuming process employed by only a few mints in the world including the Royal Canadian Mint.
Electrolysis is a two-day process whereby the gold bars are immersed in a chemical bath next to titanium plates. An electric current runs through the bath causing the gold particles to migrate to the plates while any remaining metals sink to the bottom. This step results in the remarkable .9999 fine gold used to make Maple Leaf coins.
Step 4 The .9999 gold material is thoroughly dried and melted down one last time and cast into 50-pound ingots used to make bullion coins and bars.
Step 5 Finally, the 11.5” long gold ingot is systematically compressed in a rolling mill to form a 12’ x 2.87 mm sheet of .9999 gold suitable for Maple Leaf coin production.
Step 6 In preparation for the coining press, the gold sheet is stamped into blanks. The blanks are heated again and slowly cooled. This process, known as annealing, makes the blanks more malleable and less susceptible to damage during the striking process.
Step 7 To achieve the intricate level of detail demanded by the Canadian Maple Leaf’s stunning design, the blanks are subject to massive force during the striking process.
Did You Know? ‘Pure gold’ does not occur naturally; instead, gold ore is extracted from mines and is put through a process known as refining to separate the gold from other alloys like silver. The more precise the refining, the purer the gold.
Designing and prototyping a coin is a collaborative effort between multiple talents. An artist, or team of artists, is commissioned to create the design of the coin. After the design is approved, skilled metal engravers get to work on the intricate and painstaking process of creating the master die. In order to exact consistent reproduction of the design on every coin, this process requires the same type of precision possessed by a Renaissance sculptor. With the help of specialized tools, engravers must then translate the master die to multiple working dies for mass production.
While the Canadian Maple Leaf gold coin’s original design was most likely made in a mostly manual manner, modern-day advancements in laser technology and design software impart yet another level of speed and accuracy to help these talented artists with the design and implementation process.
The Royal Canadian Mint is synonymous with quality. Multiple manual inspection opportunities are built into the refining and minting process to ensure that each coin is a specimen of perfection. Finally, each coin’s weight is inspected by an efficient automated workstation. Any coin whose weight is off by more than a fraction of an ounce will be rejected and melted down.
Did You Know? Canadian Maple Leaf gold coins are weighed three times throughout the minting process – once as a blank, another after striking, and a final time just before packaging.
Through innovative technological advancement and a commitment to the highest possible quality in appearance and purity, the Royal Canadian Mint produces some of the most illustrious gold coins in the world coveted by both first-time and seasoned investors alike. The RCM understands and respects the desires of those who invest in their Canadian Maple Leaf gold coins and that understanding is what drives them daily. As the Mint’s spokesperson, Pierre Morin simply states, “The collector wants perfection. He’s not just buying an ounce of gold, what he’s buying is a work of art in itself…”
The Gold Maple Leaf coin series is available in a variety of denominations and features unmatched purity. For more information on how to buy Canadian Gold Maple Leafs, contact a Monex account representative at 800-444-8317.
The Royal Canadian Mint’s Commitment to Quality In 1979, the prestigious Royal Canadian Mint began production of the 1 oz. Canadian Maple Leaf gold coin with a consistency of 99.9%. At the time, the only competitive private investment coin in the market was the 91.67% pure gold South African Krugerrand. The increased gold purity consistency more…
The Iconic Maple Leaf Known for its vibrant autumn colors, the maple tree is a prominent species in the eastern Canadian landscape. While the tree itself was an invaluable part of the indigenous Canadians and early settlers’ lifestyle, the Canadian government did not officially adopt the maple leaf as its national symbol until 1965.
