Never thought of antique TV game shows as source of economic inflation comparison. I grazed into a TVNZ Heartland repeat of an early 80s "It's in the Bag".
A contestant turned down $800 and took the bag. She won:
- Zip Appliance Package: Toaster, Jug & sandwich maker. Value $600
- A years supply of Petrol. Value $1500
Translate that to today and the appliances would be worth, say, $120? The petrol ~$6250!
