from a KP Numismatics promotional email: "...In 2013 the 1-ounce Canadian Maple Leaf gold bullion coin will be more counterfeit resistant than its predecessors. The Royal Canadian Mint has added what it calls an intricately micro-engraved textured maple leaf design on the lower right portion of the reverse side of the popular bullion coin."
I would think not, but it might be hard to use such a device on coins meant for circulation. The details would be gone in the first year and it would just look like a small, smooth maple leaf. Or maybe not. The tiny dates within the star on the old Spanish Peseta coins that you need a magnifying glass to read are still legible after 30+ years of circulation.
Another reason I'd like to see on in person. The photos I've seen look like it's raised, but it could be incuse. It's hard to tell in the photo.
Based on the shadows, I think the dark textured maple leaf is raised, and the smaller maple leaf on the inside seems sunken from the textured maple leaf. The "13" in the center is likely on the same level as the raised maple leaf. Either way, I'm thinking they're lower than the other details on the coin, so I think it wouldn't interfere with stacking. It also might not wear as quickly as I had initially assumed if they were to implement this technology on their $1 and $2 coins should counterfeiting of them ever become a problem. But, I would actually think they use laser engravers to create the texture on the maple leaf. If so, isn't that technology cheaper and easier to obtain than a coin press and dies?
