Your assistant is quite astute, and I concur on all points. It appears that some of the pennies are indeed post-1960. As for the coke bottle, I am not sure that Coke was even sold in bottles in this car or the adjacent diner-lounge, but if they were, it would almost certainly have been the smaller size bottle with the raised lettering. At least the cards are of proper vintage rather than having something like the screaming Eagle logo on the back.
I wasn’t going to mention it, but that cup probably should be Eagle china too.
