The dollar was pegged at $35 from 1933 to... was it 1973? In what sense had the US abandoned the gold standard in the 1930s? What is your definition of the gold standard, where the dollar pegged to gold isn't enough to mean you're on the gold standard?
It's funny how the time of the gold standard was the other time in US history where it was a banana republic but I'm sure that's a coincidence and not a collary.
What about Bretton Woods? That existed until the Nixon administration.
