1 Dollar - Elizabeth II 4th Portrait - 20th Anniversary Kangaroo Series

The Australian Kangaroo silver bullion series launched in 1993, initially conceived as a direct competitor to the Canadian Maple Leaf and American Eagle programs that had dominated the silver bullion market through the late 1980s. The 20th anniversary issue of 2013 marked two decades of annual design changes — a deliberate policy that distinguishes the Kangaroo from most bullion programs, which lock in a single reverse design indefinitely. That rotating design strategy was itself a calculated move to drive collector demand alongside pure bullion purchasing.

KM#2023 carries Ian Rank-Broadley's fourth portrait of Elizabeth II, adopted by the Perth Mint in 1999.
