Since they tag 1965 as the start, the miss the largest change in US monitory policy. Surprised no one mentions it.

Before 1965, 10, 25 and 50 cent coins made in the US was 90% silver. In 1965 all coins changed to a base metal. So that alone caused prices to rise in the 1960s to early 70s, and all silver coins disappeared from circulation.

As others mention, 1973 and the again 1978(?) the oil shock happened, which put inflation on steroids.

Nit: After 1965, half-dollar coins were 40% silver for a few years.

And, not long after, the dollar was convertible to a fixed amount of gold, either. I forget the year for that change.
