1 oz Silver Canadian Maple Leaf specifications and ping frequencies
The 1 oz Silver Canadian Maple Leaf is a silver coin from Canada (1988–2026), weighing 31.1 g with a diameter of 38 mm. Tapped gently on its edge, a genuine one rings at about 4.7 kHz, 10.9 kHz and 19.0 kHz: its first resonance frequencies, set by its metal, size and thickness. A counterfeit made of a different metal, or with a different weight or thickness, rings at different frequencies, which is what the ping test above checks.

How to spot a fake 1 oz Silver Maple Leaf
The Silver Maple Leaf is one of the best-known silver bullion coins in the world, and fakes of it turn up regularly in online marketplaces and private sales. Since 2014 the Royal Canadian Mint has struck it with security features that make good copies harder to produce, but none of them is a guarantee on its own. Several quick, cheap tests used together will catch most fakes.
What fakes exist
- Silver-plated base metal. Usually copper, brass, zinc alloy or copper-nickel ("German silver") with a thin silver coating. This is the most common type.
- Cast fakes. Poured into a mould taken from a real coin. Typically soft in detail, with a grainy surface and often wrong in weight.
- Fakes of pre-2014 dates. Older coins have no radial lines or micro-engraving, so a counterfeiter has less to copy.
Because silver is far less valuable than gold, elaborate dense-core fakes are rare. Most silver fakes are simply the wrong metal, and the tests below are good at finding that.
The checks, in order of usefulness
1. Weight
Use a scale that reads to 0.01 g and compare with the weight in the facts box. Silver is denser than copper, brass or zinc, so a plated base-metal coin of the right size usually comes out light. A coin that is clearly off is a red flag. A correct weight on its own doesn't prove much, so carry on with the other checks.
2. Diameter and thickness
Measure with digital calipers. A base-metal fake made to the correct weight has to be thicker or wider than a genuine coin; one made to the correct size will be too light. Getting both right with the wrong metal is hard, which is why weight and dimensions together are so useful. Check thickness at a few points on the rim, and note whether the coin fits a standard Silver Maple capsule.
3. Security features (2014 and later)
From 2014, Silver Maples carry two features:
- Radial lines. Very fine lines radiating from the centre across the background on both sides. Tilt the coin under a single light: the lines should create an even, shimmering reflection. Missing, broken, uneven or coarse lines are a warning sign on a 2014-or-later coin.
- Micro-engraved maple leaf. A tiny laser-engraved maple leaf on the reverse with the last two digits of the year inside it, visible with a 10x loupe. It should be sharp and the digits should match the coin's date.
A Silver Maple dated 2013 or earlier shouldn't have either feature. That is normal and not a sign of a fake.
4. Magnet slide
Silver is not magnetic, but it is a very good electrical conductor, so a strong neodymium magnet slid down a tilted coin is slowed noticeably by eddy currents. Tilt the coin at about 45 degrees and let the magnet slide down it.
- Magnet sticks: fake, with iron or steel in it.
- Magnet slides slowly and steadily: consistent with silver.
- Magnet slides quickly with little braking: suspicious; many base metals and alloys conduct less well than silver.
Copper also conducts well, so a copper-core coin can show some braking. Use this as a screening test, not proof.
5. Design, surface and edge
Under a loupe:
- Reverse: the maple leaf veins should be crisp and evenly deep. The lettering "FINE SILVER 1 OZ ARGENT PUR" and the "9999" mark should be clean and evenly spaced.
- Obverse: the portrait must match the date: Queen Elizabeth II up to 2022, King Charles III from 2023.
- Edge: even reeding all the way round, no seam and no change in colour that could show plating.
- Surface: cast fakes often look grainy or pitted. Silver plating can wear through on high points or the rim, showing a coppery or yellowish metal underneath.
Genuine silver can tone or develop milk spots over time. That's cosmetic and doesn't indicate a fake.
6. Ping test
Balanced on a fingertip and tapped gently, a genuine Silver Maple gives a clear, long ring. Plated base-metal fakes often sound duller or shorter, or at a noticeably different pitch. Use the ping test at the top of this page to compare the coin's ring with the frequencies expected for a genuine Silver Maple.
The ping test is one strong check, not a final verdict. Room noise, how the coin is held, a bent or damaged coin, or testing inside a capsule can affect the result, and it could miss some fakes. Use it alongside weight, measurements and the magnet slide.
7. Ice test, specific gravity and XRF
- Ice test: silver conducts heat exceptionally well, so an ice cube placed on a genuine coin melts noticeably faster than on glass or a base-metal coin. Copper also conducts heat well, so treat it as a rough screen.
- Specific gravity: weigh the coin in air and then suspended in water; the ratio should be close to that of fine silver. This is a good test for plated fakes.
- XRF or a conductivity tester, available at many dealers, gives a more reliable answer if you're still unsure.
Date-specific tells
- 1988–2013: .9999 silver, no radial lines or micro-engraving.
- 2014 onwards: radial lines and the micro-engraved maple leaf.
- 2023 onwards: King Charles III portrait.
Any mismatch between date, portrait and security features is a red flag.
If you suspect a fake
- Stop. Don't sell it, trade it or pass it on.
- Re-run the tests and add the ones you skipped: weight, calipers, magnet slide, loupe, ping test.
- Take it to a reputable dealer for a second opinion or an XRF check.
- If it is fake, contact the seller and the platform you bought through, keep the records, and report it where appropriate.
Buying from established dealers with a return policy avoids most problems. Prices well below what other dealers charge, or sellers who refuse returns, are warning signs.
