20 Dollars - Charles III Savage Vikings

Cook Islands has become one of the more prolific issuers of high-relief collector silver under licensing arrangements that have little connection to the territory itself — this "Savage Vikings" piece is part of that broader numismatic publishing model rather than any domestically driven commemorative program. The .9999 fineness is notably purer than the .999 standard common to most sovereign bullion, a specification choice that marginally softens the alloy and can affect die life at the strike pressures required for deep relief work.
