For initial analysis of coins we use Reece periods, named after the pre-eminent Romano-British numismatist, Richard Reece. He divided the Roman period in 21 periods (Sam Moorhead has added two more) for the purpose of comparing different sites. You can find out which rulers fall into different periods and search the database accordingly. Obviously, to carry out effective analysis by Reece period, we need to record ALL the coins from a site.
