It's too bad that I was mainly interested in British coins back then, because I doubt that I looked closely at their ancient coin section. It's not as if I had a lot of money to spend at the time, but given the prices, I certainly could have picked up a decent number of Roman coins over the course of a few months. A couple of things I notice: almost all the coins are described as F or VF; very few as EF or better. (I'm sure that they weren't targeting top-of-the-market customers -- they weren't Stack's, to mention one place that sold and auctioned high-end coins back then in New York -- but they weren't Gimbels, either. I suspect that an equivalent place today would describe its coins much more generously.) In addition, I see that despite a few references to BMC and RIC, almost all the catalog references are to Cohen. Even in 1971, it must have been seen as more accessible to people, at least in the USA, than BMC or RIC. Here are copies of the first page of the catalog, and the 5-page ancient coin section (which was all Roman, including some Roman Provincial; no Greek coins at all).
