Julia Domna coin.

Hi all, I need a little help with a Julia Donna coin. On the reverse it has the letters ETI or maybe PTI. The only god/goddess with those letter in the name is Laetitia. god/goddess seated holding sceptre and child. Apologises for the unclear image. Any info greatly received.

Rarely seen Mars seated, but given how short the legend is...
Could be Marti, and cornucopia instead of child?
Would be a weird one for Domna though.

Hello,

Not sure about what I see but could it be a fourree coin? It looks so on the pics. If it is, the reverse legend could be an engraving error.

Thank you.
ive had a look at hundreds of Julia Domna coins including fourree coins. The closest I’ve got is on Wildwinds. Reverse image correct but legend is Pietas.
Completely stuck.
