Ignoring the face that there's a full box of 1979 for $999 on eBay, making $200 ridiculous for a pack, for a moment:
Average Price for gasoline in 1979 was $.086
Price of a 1979 Wacky Pack was $0.20
Making the pack worth 23.25% of a gallon of gas at the time when the pack was box-fresh, Minty-Mint PSA10.
In CA, I'm paying around $6.50 per gallon (yah, sucks)
So, doing the math... that pack should go for about a buck-fifty ($1.50) at the most.
Well... unless the price of a VINTAGE gallon of gas saved in a canister from 1979 (preferably purchased at a Stuckey's) has gone up to $860...
If the zombies keep multiplying, I think I'd rather have the $860 can of gas than the $200 pack at this point.
