Can anyone tell me what this is?

1. What is on the other side - and a picture. 

Even if it is the same, at least tell us. 

2. What is the diameter. 

 Guessing it is 30mm - like these two, the same both sides … 

N#54332 

N#75633 

Sorry 😂 it’s the same on both sides. No lettering or numbers. Very light. I’m thinking it may actually be a token of some kind

 Found by cropping your one picture, then putting it in the Search … 

Sorry I’m new to this. I’m not a coin collector, I just came across this in a bag of old shillings that my grandad had and was curious as to what it may be 

 OK - and 1 minute before your first reply I added links to two of them. 😊 

Thankyou! Appreciate it.

Im embarrassed to say that I still have no idea what it actually is 😂 A token but a token for what? How old may it be? Does it have a worth or is it just a cool coin to keep.

I make a novice look like an expert!
