cash identification

Hello,
I wonder if this coin is a replica, and if anyone knows how to identify.
Thank you
Andrea

Thank you for your answer.
Which book did you get the information?
Based on the pictures you think that coin is the original or a replica?

It's the Hartill cash book.
When you'll reference your coin on Numista, the ref number is: DH# 22.922

As this coin is not very old, I would rather say your coin is genuine. But I'm not skilled to separate the wheat from the chaff.

Thanks again for your help
