The World's First Traceable Gold Coin? The Royal Canadian Mint's 2015 Maple Leaf

The Royal Canadian Mint unveiled its 2015 Gold and Silver fractional coin sets this week with several numismatic "firsts" as features of the coins.

Both sets are 99.99% purity and come in weights of 1/20, 1/10, 1/2 oz, and 1 oz denominations. The silver set will consist of 5 coins with an additional 1/4 oz piece included.

The gold coin set will feature a different design on each coin of a maple leaf in different stages of falling through the air. The 1 oz  coin will be the first gold coin to feature a unique serial number engraved along its edge.

Each coin will also feature a reverse proof finish and contain the effigy of Queen Elizabeth II designed by Susanna Blunt.

600 units of each gold set will be minted.

The silver fractional set will come in 5 different weights and be struck with an "incuse" technique which imprints the image beneath the surface of the coin. The 1oz silver coin will also feature a translucent red enamel on the maple leaf design, highlighting the contours of the engraving in vibrant color.

The silver set will also have a reverse proof finish and feature an effigy of Queen Elizabeth II.

9,999 silver sets will be minted.

Both sets will come packaged in a clamshell case and lacquer beauty box and can be purchased directly from the Royal Canadian Mint's website.
