Constantine I VICTORIAE LAETAE PRINC PERP from Trier

[Victor]

here's a nice example of this silvered type...much rarer than its billon counterpart struck in A.D. 313

Constantine I
A.D. 318-319
Silvered nummus
18mm      3.2g
IMP CONSTANTINVS AVG; high crested helmet, cuirassed, spear over right shoulder, in l. parazonium(?).
VICTORIAE LAETAE PRINC PERP; two Victories stg., facing one another, together holding wreath inscribed VOT PR on altar.
In ex. PTR
RIC VII Trier 208A

Ex Brian Henry Grover Collection

[Heliodromus]

Very nice coin, but what makes you think it's not the 313 AD 20% billion ?

From both the surface appearance and bust style, I'd guess it is the 313 AD one (and I also think the initial - but not subsequent -  Trier issue in 318-319 may have been officina "S" only to avoid confusion).

You can see areas where the silvering is not present. I will have it in hand soon.
