Note:
(1) Il denario adrianeo pesava 3,21g (come media su 733 campioni); peso di picco 3,17g. Esso aveva un contenuto di fine dell'ordine del 75-85%, il resto della lega essendo costituito per lo più da rame. Di seguito riporto le caratteristiche fisiche di quattro denari del British Museum appartenenti alla serie monetale di figura (essi differiscono tra loro per alcuni particolari del busto di Adriano) e di tre denari classificati dal sito dell'ANS (http://www.amnumsoc.org/search/)
