Considering that the majority of inventory was and still is available outside of the hobby; along with approximately 50% of the total number of sets (4000 of the 200-300 pc sets)... there sure seems like after the 20++ years after distribution that there is a shedload of them out there even discounting what may have been discarded during those many years... which, appears that the original production may have been a failure due to lack of interest or simply not marketed properly... unless my math is wrong... 200,000 chips ÷ 250 chips per set = 8000 sets.
