Indulgence Flights to USA in 1960

[Warmtoast]

I'm preparing a piece for PPRuNe about a trip I made to the West Coast of the USA and back in 1960, indulgence flights both ways. However, for parts of the trip (New York to Washington and Los Angles to San Francisco) I had to travel by Greyhound bus and wonder are there some experts out there who know how much the fare would have been by Greyhound bus in 1960 from:
a. New York to Washington
b. Los Angles to San Francisco
TIA

Not a specific answer to your question but I recently found a Greyhound ticket in a box of ancient documents in my garage. It is from Santa Barbara to San Jose (north of LA to south of SF), and I do remember the journey on a sunny day in Sept 1974. The ticket does not contain any pricing info, but I do remember it could only be described as "very reasonable". I did the Toronto- Detroit trip earlier that month, and that was the same.
