Two Unknown Roman Billon/Silver Coins (Solved)

Thank you!

Yep, both Gallienus, both from the East.

#1:
Antoninianus. Mint of "Asia"
GALLIENVS AVG, radiate cuirassed bust right / VIRTVS AVG, Soldier standing right, holding spear left, leaning on shield right, PXV in ex.
Gobl 1666k, Sear5 10403, RIC V-1 612

#2:
Antoninianus, Sole reign. Antioch.
GALLIENVS AVG, radiate, draped and cuirassed bust right / SOLI INVICTO, Solus standing left, holding whip, right hand raised.
RIC V-1 (S), Asian Mint 658; Sear 10364.

Without reading research info, I can only guess at a reason.
I suspect that a lot of them were hoarded and hidden for military reasons, only to be recovered in modern times.

Gallienus has lots of coinage readily available due to a perfect storm of circumstances: debasement had left the empire needing ungodly volumes of coinage, his reign was long and there was a healthy amount of time until the coinage was reformed under Aurelian* and the currency begun to be replaced. During this period of time, the empire was experiencing some significant turbulence and so a lot of hoards were deposited. The low value of the coinage also necessitates large hoards.
