Can anyone tell me how exactly Sear's relevant volume is organised? I only have the second volume covering Nerva until the end of the Severans, and obviously the situation with the mints was far less complicated during that period. Is it relatively simple to be able to find parallel issues from different mints from roughly the same time period? Also, I don't expect it to be comprehensive, but are a wide variety of mintmarks presented within the catalogue, along with the relevant weight alterations, or is there only one entry, for example, for the Soli Invicto Comiti 'type' at a certain mint, with the variety of mint marks using that type noted in one entry? Many thanks.
