roman Antoninianus 2 [επιλυμένο]

ortalama 3 gr

It's one of these three: https://en.numista.com/catalogue/index.php?e=rome&r=&st=1-2&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=215-301&i=*MARTEM+PROPVGNATOREM*&b=&m=1&f=&t=&t2=&w=&mt=&u=&g=&c=&wi=&sw=

I think this is the most likely:
N#283598

The end of the obverse text seems to be PF AVG and this is the only one of the three with that lettering.

en çok bunu merak ediyordum. size çok teşekkür ederim. görsel hafızanızla mı buluyorsunuz yoksa başka bir yolu var mı ?

No, usually I just read the text and run a search with a partial match. For example, part of the reverse of the coin is readable, I can see “ATOR”. Running a search with the issuer as the Roman Empire, date between 215-301 (because this is an antoninianus), composition as silver, an the lettering as *ATOR* only gave me 200 something records:

Those can be browsed though relatively quickly. If you focus on the obverse figure, there is a very similar one on the second page. So I just modified the search from a partial text match to *MARTEM PROPVGNATOREM*, which yields only 3 records. After that, it's only just spotting a difference between those.
