Antoninianus - Tetricus I with or without altar?

Hello, I recently bought this roman coin.
I am new to the topic of ancient coins so this question might seem a little bit stupid but...

Is this the version with or without the altar?
They are both listed on numista, I just cant seem to figure out the difference.

My coin:


I know that it is a very common coin, as I said this is my first ancient coin (and the first coin I bought in general).
Any information given is much appreciated^^

Yes

There are multiple examples of variants within RIC 126 and 127 on WildWinds but as far as I can tell none of them mention "without altar". Check https://www.wildwinds.com/coins/ric/tetricus_I/t.html and try to find yours.

I said "with" and "without" altar because it is in the numista article, if "without" doesnt exist it will be "with" then.

I know almost nothing about browsing coin catalogues and the different designations for coins that exist, I guess I will put it in said category for now.
