300 Dollars - Elizabeth II Atlantic time

Part of the Royal Canadian Mint's five-coin "Time Zones" series, this issue commemorates Atlantic Standard Time, one of Canada's six official time zones — a bureaucratic boundary that has caused friction since the Dominion first attempted to standardize time in the late nineteenth century. The bimetallic 14-karat gold-and-silver composition, unusual for a Canadian commemorative of this period, was chosen deliberately to give each coin in the series a warm, two-tone appearance distinct from standard gold issues.

Nova Scotia and New Brunswick are the primary Atlantic provinces; notably, Newfoundland maintains its own offset of UTC−3:30, meaning it technically falls outside Atlantic time entirely.
