1 Dollar - Elizabeth II Imperial Desk Clock

Niue has functioned since the 1990s as a licensing vehicle for the New Zealand-administered commemorative coin market, issuing legal tender under its own authority while bearing no practical monetary relationship to the island's 1,600-odd residents. This piece is a clock insert — a functioning timepiece embedded in the coin itself — a format that creates immediate problems for long-term preservation, as the quartz movement requires battery access and will eventually leak.
