The "GML" designation refers to the Geo-Metrical Lenticular technology developed by the Royal Canadian Mint, a micro-engraving security feature that produces a shifting maple leaf image visible only under direct light at specific angles. Introduced as part of the Mint's broader anti-counterfeiting push in the 2010s, it distinguishes this circulation-adjacent bullion issue from the standard Maple Leaf series. The .9999 fineness — four nines — was itself a marketing and metallurgical achievement the Mint pioneered decades earlier, pushing purity beyond the .999 standard that most competitors held.
