Cash coins identification [solved]

Hi, i would ask your help to identify correctly the following coins, and your opinion about authenticity.
Thank you very much for your help.

from left to right
1) 8,00 gr - 28 mm
2) 3,83 gr - 27 mm
3) 6,55 gr - 28 mm

Hi,

The identification for these coins as below

Left: DH#21.7
(No page has been created for this coin in Numista)

Middle: DH#22.70
https://en.numista.com/catalogue/pieces7319.html

Right:
https://en.numista.com/catalogue/pieces15835.html

However, I am doubtful for the authenticity of the coins base on the following observations:
- Calligraphy for the coins looks strange
- According to the David Harill, the left coin has rarity of 2, which means it should be not commonly found

I would suggest the following tests:
- Put the coins inside the boiling water for several minutes, if any colorings comes off that means the coins are counterfeit
- Sniff the coins and find out if there is any irritating chemical or strong metal smell.

Thank you. I am doubtful also because of inscription in coin 2 and dimension in coin 3. I will try your suggestions
