100 Dollars - Elizabeth II Arnold Palmer

Arnold Palmer won the 1954 U.S. Amateur at the Country Club of Detroit, then turned professional and became the defining face of golf's television age — his popularity in the late 1950s and 1960s was largely responsible for establishing the sport as a mass-broadcast property in the United States. The Solomon Islands has issued large-format silver kilo pieces under its $100 denomination repeatedly since the 2010s, using the Central Bank's issuing authority to produce bullion-adjacent commemoratives with no meaningful domestic circulation.

Palmer died in September 2016, making this a posthumous tribute struck four years after his death.
