Sorry, I must have forgot where I was. 
I seem to recall gasoline priced about 20 cents a gallon in the early 60’s. The reason I remember is b/c as a kid then I would always ask my parents what the “9” at the end of the price meant. The sign didn’t say 20 cents a gallon, but 20 and 9/10 cents a gallon. On the sign the 9/10 was just a 9 as a superscript above the 20. “What does that last “9” mean?” I’d ask. This question at every gas stop would frustrate my dad b/c he had some difficulty trying to explain, so eventually he said “It doesn’t mean anything!!!” … lol …
Penny candy was definitely a thing then. You could get a lot candy for 20 cents, very true. One time my school friend’s family was going to Las Vegas for a few days holiday, and he asked if they could take me along so he’d have a buddy to hang around the hotel pool with while the parent gambled. The first afternoon the dad showed us a slot machine. He pulled out a quarter from his pocket, showed it to us. He was trying to show us the evils of gambling. Showing the quarter, he said “This will buy you 25 pieces of candy, but just watch what happens when I put it in the slot machine.” Whirrrrr whirr whirrrr goes the wheels. Jackpot!! $10!!! … lol …
I guess gas price depends on where you lived. I recall 12 cents a gallon, and I think that was the late 1960s. That was before I had my license, and I didn’t pay a lot of attention to gas prices until I had to buy gas.
Ah, the good old days. When in college, three things cost the same; a fill up for my 48 Chevy, a case of 24 beers and a good bottle of whiskey. All for about $3 or so.
The gas is now $40 or so for a fill up, and the bottle of booze is still only $22 while the beer is about $25.
Of course my summer job only paid $400 per month.
