The 2013 $3 Fine Silver Coin – Maple Leaf Impression was a limited edition coin produced by the Royal Canadian Mint. It was struck in 99.99% pure silver and had a weight of 7.96 grams. The coin featured a design of a maple leaf with a unique impression in the center, which was created using a special minting technique called “micro engraving.” This technique creates a tiny, detailed image on the coin that is visible only under magnification, making it a highly collectible and valuable piece for coin collectors.
