My first thought was it was a AE sestertius of Vespasian with the Emperor on horseback on the reverse but the condition is less than perfect.

That forehead could only belong to Domitian. I think you have the reverse slightly rotated - it is likely this sestertius of a rearing horse:  Couldn't find a picture of a nice example that I could link, but Wildwinds has some good examples of the type. |

I would leave it as is - I don't think there is much detail to be revealed, but the surfaces under there might be rough. Is the darker green stuff loose?

The similar coin leads me to think 'Domitian' as well.

the greener part on the face is harder, the clear green part melts easily. Do you recommend taking a little lemon bath? With other copper coins, lemon was better than EDTA

Cleaning the green off may? not help facilitate the identification.
The coin is in poor enough condition to risk a cleaning.
In this condition; it shouldn't be stored next to other bronze or copper coins anyway. Bronze disease is contagious.
I say clean it. Nothing ventured, nothing gained.
Try VerdiCare first, but probably won't help.
Next, look on Google for treatment for verdigris. Pick a method which best suits the needs of the coin to help with identification.

Mistakes are made often when learning! The issue here was the use of lemon - citric acid never has a place when cleaning bronze. For silver, it is often useful, but for bronze, as you have found, it does more damage than good every time.
But, the good news is that there is further learning to be had - perhaps break out a bamboo skewer or a toothpick and try carefully working down the darker green around the rider.

If nothing else, it would be a useful cautionary tale that we can point to when someone else is asking about lemon juice--a chance for someone to learn from your mistake!

Even museum curator professionals have ancient coin cleaning failures occasionally.
What works on some coins can be wrong for other coins.
And there is no way of finding out for sure, beforehand.
A lot depends on the environment over centuries to which the coin has been exposed, which, in many cases, can only be guessed at.
