Roman coin 1 [solved]

Hello, i have been given three roman coins and jave been attempting to identify them. The first is the one below that i believe is N#288615, though I feel like the design is a bit different and I'm not to sure on the lettering either. I've seen similar coins on different sites as well. Any information or confirmation would be appreciated. 

 Similar - https://coincraft.com/gallienus-griffin-coin 

GALLIENVS AVG // APOLLINI CONS AVG  

 with a standing griffin facing left on reverse, mintmark Δ below.  

 So yes either 

N#288615 [with pictures] 

 or the next page 

N#288616 [without pictures] 

 whatever the difference is. 

Could be some other coin not on here yet, but lettering matches. 

Thank you
