The 350 remaining coins of the Woodeaton Hoard have been analyzed by x-ray fluorescence to determine the variation in alloy content of fourth century Roman copper base coins between mints, the variation through the fourth century, and the composition of the contemporary forgeries included in the Woodeaton hoard. Analysis showed that the silver content was reasonably constant at just over 1%, as was the tin content at around 11/2 to 3 percent. The lead content was much more variable, quantity over 10% being comon. There was little variation from mint to mint, but quite a lot with time. The forgeries only contained traces of silver and tin but often large quantities of lead.
