Unknown Roman Coin #3 [solved]

Hello all, 

I have a coin here that I believe is from the Crisis of the Third Century, though the emperor is hard to determine. The coin is around 2.65g and around 18mm. 

Hope to hear where this is from!

The reverse is MARTI PACIFERO, which is used by a bunch of emperors: https://en.numista.com/catalogue/index.php?e=rome&r=&st=1-2-79-80&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=215-305&i=*marti+pacifero*&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

The obverse is very worn, but it's maybe Gallienus? N#289148

Appears to be under Gallenius as there are some missing features on this coin that are found under different emporers. 

Thanks!
