Both the Coronation as well Persepolis, respectively 1967 and 1971, were before the world wide oil crisis of 1973.
Remains: a theatre with a diamond encrusted Peacock Throne, a Shahbanou with sapphires as big as our eyeballs popping out. And that in a -to western standards- underdeveloped country. And by an "imperial" dynasty which is rooted in.... 1941.
I really love a good show. On the right time and in the right place that is. The Shah had to avoid this. This was deadly for his reputation. A good reputation comes by feet and runs away on horseback. The Iranians I know, very opposing the present Islamist regime, are as negative towards the Pahlavis. There is no love lost, is my impression.
