300 Dollars - Elizabeth II Ontario Coat of Arms

Ontario's coat of arms was granted by royal warrant in 1868 — just one year after Confederation — making it one of the oldest provincial armorials in Canada. The 2013 issue is struck in electrum-style bimetallic gold, a 14-karat alloy that the Royal Canadian Mint has used selectively for large-format collector pieces where cost and visual warmth both factor into the decision. At 60 grams, the planchet carries enough mass that the alloy's lower fineness is less commercially awkward than it might appear on a smaller coin.
