Watch List notes:

Claudius. AD 41-54. Æ Quadrans (19mm, 3.38 g, 6h). Lugdunum (Lyon) mint. Struck AD 41-42. Laureate head right / The Great Altar of Lugdunum: altar enclosure; panels decorated with corona civica flanked by figures holding laurel branches; altar flanked by columns surmounted by statues of Victory standing vis-à-vis, each holding palm frond and wreath. RIC I 1; Lyon 90. Brown patina, roughness, a few scratches, reverse slightly off center. Fine. Very rare, only three specimens at CoinArchives.

This was Lyon's final issue depicting 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 may have been issued to commemorate Claudius's fiftieth birthday.
