Ultra high relief has allowed us to take coin designs to greater heights than ever. And now we've added incredible depth to our latest engineering marvel: a 13-sided (tridecagon) coin-sized replica of the Centennial Flame monument on Parliament Hill. The realistic rendering was made possible by a dramatic variation in relief height: the deep sunk basin gives this coin a minimum thickness of 1.51 millimetres, which soars to 5.05 millimetres when measured from the tip of the engraved flame. An antique finish also gives this coin a more weathered appearance—like the granite-and-bronze fountain that celebrates Canadian unity.
