Hard to say... I'm gonna say it is real based on the details im seeing. It is damaged however, corroded. Im not ruling out a contemporary counterfeit either though. Heavy wear in the central devices on the obverse stand out to me like someone was trying to hide something. I dont see anything crude about the devices suggesting hand carved dies or cast, but again hard to say with the apparent corrosion. You are gonna have to weigh it in grams. Maybe that will tell a little more about it.
Here is an example from CoinFacts Placement looks ok to me. Again, weighing it would be the next thing to do.
It’s real ugly but I can’t call it either way. Weight should be close to 26.2 g too many of the determining factors are too worn or damaged to tell. But I don’t like the overall central weakness of the obverse personally
