Watch List notes:

Claudius (41-54), quadrans, Lyon, 41-42, TI CLAVDIVS CAESAR AVG P M TR P IMP, laureate head right, rev., ROM ET AVG, altar of Lugdunum, 3.19g (RIC 1; BMC 227; Giard 90; BN 98-107; C. 81), some pitting, brown patina, good very fine, very rare. This is the last issue of Lyon to depict the altar of Lugdunum dedicated by Augustus on 1 August 10 BC which, as RIC notes (p. 115), coincided with the birth of Claudius at Lyon. If struck in 41 it would perhaps have been issued to commemorate Claudius's fiftieth birthday.
