50 Dollars - Elizabeth II 90th Anniversary of WWI

Solomon Islands issued this coin in 2008 to mark the 90th anniversary of the November 1918 Armistice, though the irony of the issuer is hard to ignore — the archipelago was not a combatant in WWI, and wouldn't become a battleground until the brutal Guadalcanal campaign of 1942–43. The Solomon Islands' numismatic program has long used commemorative silver to generate revenue, with themes bearing little direct connection to local history.

KM# 43 is a large-format five-ounce piece produced for the collector market and almost certainly never circulated.
