Wrong RIC reference

For this coin
https://en.numista.com/catalogue/pieces41291.html
the RIC# 181 reference is wrong

because Constantinus II RIC# 181 is "VICTORIAE LAETAE PRINC PERP - VOT/PR"

Constantinus II BEATA TRANQUILLITAS, Lyons mint references are
RIC VII 148
RIC VII 181 var
RIC VII 188 var
from

Your post is by itself a contradiction. You say it's wrong but also later it's right.

And it seems you had a confusion between Lyons/Lugdunum and London/Londinium.

In RIC VII coins are separate not by Emperor but by mint. This explains why Constantine II has 2 RIC#181 references.
