I can confirm that the coin is not a counterfeit. I received it as a gift from an archaeologist who excavated the coin many years ago, and it has been properly documented with details regarding its origin and the location where it was discovered. Given this, I have no reason to believe that it is fake.
Unfortunately, I do not recall the coin's identification number, which prevents me from conducting further research on the government website. However, if you have any concerns regarding its authenticity, I would appreciate any additional insights you may have.
Thank you for your attention to this matter.
Best regards,
Marko
