What is the 1oz Maple Leaf Gold?
The 1oz Maple Leaf gold coin is one of the most famous and popular investment coins worldwide. Since its introduction in 1979, it has earned an excellent reputation for its high quality and purity. The gold coin is minted by the Royal Canadian Mint and is known for its purity of 99.9% gold, and since 1983, an impressive 99.99%. This coin is one of the first modern investment coins and has found a permanent place in the portfolios of many investors and collectors since its introduction.
The Maple Leaf is not only a valuable investment, but also a work of art that reflects Canadian culture and nature.
Obverse
Until 2023, the obverse of the 1 oz Maple Leaf gold coin featured a portrait of Queen Elizabeth II. The portrait on the right was designed by Canadian artist Susanna Blunt and has been in use since 2003. Below the Queen's portrait is the coin's face value in Canadian dollars (CAD) and the year of minting. From 2024 onwards, the portrait of Queen Elizabeth II was replaced with that of King Charles III.
Reverse
The reverse of the coin features the iconic Canadian sugar maple leaf designed by Walter Ott. This leaf, known worldwide as a symbol of Canada, is the centrepiece of the coin and gives it its name. The word ‘CANADA’ appears above the maple leaf, while the fineness and weight of the coin are indicated next to the leaf and below it: “9999” and ‘FINE GOLD 1 OZ OR PUR’. In addition, since 2013, a small maple leaf and radial lines have been engraved as security features to make the coin more difficult to counterfeit.
Prüfung der Münze
In this example, the coin is measured based on three characteristics: diameter, weight and electrical conductivity. These three measurements together provide a comprehensive assessment of the coin. Watch the video! (YouTube)
Dimensions & weight
The coin weighs one troy ounce, which is equivalent to 31.103 g. It also has a diameter of 30 mm and a thickness of 2.87 mm. These values are confirmed in the video using a precision balance and a digital caliper. These values were used to determine the approximate density.
Alternative method of determining density
As an alternative to these measurements, another method can be used to determine the exact density, namely density determination according to Archimedes' principle. This is very easy to implement with the DensityScreenScale. For pure gold (999.9/1000), a density of 19.32 g/cm³ is expected. However, since the density of gold can be easily imitated using tungsten, it is ultimately worthwhile to measure the electrical conductivity of the coin.
Conductivity measurement
The 1oz Maple Leaf gold coin is made of the purest gold (999.9/1000). The GoldScreenSensor is particularly well suited for accurately measuring the conductivity of this coin, as it enables precise analysis. The electrical conductivity of pure gold (999.9) is approximately 45.0 MS/m. This expected value was confirmed in the video. In summary, it can be said that the authenticity of the coin was confirmed by the combination of dimensions + weight and electrical conductivity.
Used products
Goldanalytix GoldScreenSensor – the product features at a glance: Gold test device for quick and simple authenticity tests of gold and silver Suited for coins and ingots from about 1/4 ounce up to one ounce / 50g (also in capsules or blisters) Simplyfied measurement mode supports by alloy assignment Immediately identifies also the frequent and very dangerous counterfeits made of tungsten or tungsten alloys (this material has the same density as gold) Suited for mobile applications - fits in almost every pocket! You want to be sure that all that glitters really is gold (or silver) and not be victim of one of the numerous precious metal forgers? If the answer is yes, the GoldScreenSensor by Goldanalytix is the correct precious metal tester for you. This electronic gold tester for the pervading authenticity test of precious metals gives you safety when trading precious objects. The GoldScreenSensor establishes the genuineness of precious metal coins or ingots within seconds - even through caspules and blisters. The test is simple and straightforward: 1. Place object on the sensor field; 2. Wait for the result (gold and silver alloys, platinum, palladium or typical materials of counterfeits are displayed); The application fields are numerous: for precious metal traders, for bancs, for private sellers, second-hand markets and all other occasions of the precious metal trade. The advantages of the "GoldScreenSensor gold test device" are among others: + quick and pervading authenticity test (goes through gold layers that often are plated on the outside and discovers the counterfeit core) + avoidance of high financial losses caused by buying false gold or silver + avoidance of legal consequences (those who sell counterfeit precious metals have to prove that they haven't been put them into circulation) Perfect for buying and selling precious metals! If you are not sure about some objects or the result are not as expected, you can find out the nature of these objects by using the conductivity charts. The penetration depths depend on the metals' electrical conductivity - up to 650 µm on each side in case of .900/.916 gold - so in total 1.3 mm, about 250 µm for pure silver and 350 µm for pure gold. Thanks to the analysis of numerous counterfeits, we know that the GoldScreenSensor is suited for objects up to 50 grams, for which the thickness is the limitin factor. The GoldScreenSensor can test coins from 1/4 ounce on and bars from 10 grams on (The measuring coil has to be fully covered). For smaller and/or unevenly shaped objects (nuggets, scrap metal, dental gold and so on), we recommend our "GoldScreenPen".
