100 Dollars - Elizabeth II Javelin

Cook Islands issued a series of platinum Olympic sports coins in the lead-up to the 1996 Atlanta Games, of which this javelin piece is one. The series exploited a well-established arrangement: Cook Islands, a self-governing territory in free association with New Zealand, has no practical domestic coin circulation, making its numismatic program essentially a licensing operation run through foreign distributors since the 1970s.

At 7.78 g of .999 platinum, the coin tracks closely to a quarter-ounce bullion weight — a deliberate choice that made pricing against spot straightforward for the investor market these were explicitly aimed at.
