2 Dollars - Elizabeth II Star Trek: The Original Series

Perth Mint's licensing arrangement with CBS Consumer Products has produced a long run of pop-culture silver issues, but this particular release belongs to the wave of Trek collectibles tied to the franchise's 50th anniversary promotion cycle that extended into 2018. The coin was struck in a mintage of 10,000 pieces — low enough to sustain secondary market demand but high enough that artificial scarcity isn't the selling point.

The face value of two Australian dollars is nominal; no one has ever tendered one of these at a checkout.
