5 Dollars - Elizabeth II Steffi Graf

Niue's 1987 collector series capitalized on Graf's extraordinary season — the year she won three of four Grand Slam titles and finished ranked world number one, a position she would hold for a record 377 weeks over her career. The island territory, a self-governing state in free association with New Zealand, had essentially no domestic coin circulation economy, making these issues purely revenue-generating instruments sold directly to the collector market.

KM#5 is one of several celebrity sports issues Niue produced in this period, a practice that drew some criticism from numismatic purists at the time.
