In 1995, Mattel launched a special series within Hot Wheels called Treasure Hunts. The initial 1995 release featured a limited production run of 10,000 units for each vehicle. Responding to collector demand, the 1996 set increased production to 25,000 for each car. Subsequent years kept production quantities undisclosed, but the elusive nature of these treasures persisted. Recognizable by a distinct green bar on the card packaging, these exclusive Hot Wheels are labeled "Treasure Hunt" or "T-Hunt," adding an extra layer of allure for avid collectors.
