20 Dollars In the name of George V, WWI - Newfoundland

Newfoundland never actually issued a $20 coin during George V's reign — or any reign. The denomination is fictional, a modern invention by the Royal Canadian Mint packaging Newfoundland's WWI contribution into a commemorative format that has no historical monetary precedent. Newfoundland did maintain its own coinage series through 1936, but the largest denomination struck was the fifty cents.

By 1918, roughly 12,000 Newfoundlanders had enlisted — from a total population under 250,000 — and the Newfoundland Regiment's near-annihilation at Beaumont-Hamel on July 1, 1916 remains the defining national trauma of that war.
