does anyone recognize it?

 Pictures cropped. What is the diameter? 

 There is OPTIMO PRINCIPI on the reverse, 

with maybe  S P Q R before it, above a figure with a raised right hand. 

 Something like this, but with a much larger portrait. 

N#253508 

To me the bust looks like that of Claudius Gothicus, certainly not Trajan.

The low detail and porousnes also makes me think it might be a cast fake.

Hard to say without size & weight.

What's up with those scratches next to the bust?

The reverse does indeed look like the one identified by ZacUK. Perhaps a barbarous imitation? 

Or indeed a cast.

I think it is a modern tourist fake. It looks to have been cast, not struck. 

Obverse is Hadrian, but he did not mint any SPQR OPTIMP PRINCIP coins; Traianus did. So obverse Hadrian, reverse Traian, cast: perfect recipe for a fake touristic coin not to mess with real stuff in the museums. Somebody obviously vandalized the coin so that it would look more ancient:):):)

Unfortunately, I caused them 5 years ago. I found it then, and now I looked up what this coin actually is! its weight is 14.61g
I will write down its diameter tomorrow!

I'm talking to a translator, sorry if I don't describe something the way I want it to

i don't know 

Yours look bronze too (copper material, brown/orange from your photos) but I am definitely sure it is not a real coin but a modern fake. No such coin exists in antiquity. But maybe I am wrong. Take it to a museum.

gold

Sorry, but yours does not look like gold. It is obviously “orichalcum” or simply “brass”. 

And anyway, I still believe your coin is a fake, worthless, modern junk. I suggest you take it to a museum to learn more about it.

I second this.
