Diammeter of Zanzibar coin [opgelost]

Hello experts!

My Zanzibar coin below:
https://en.numista.com/catalogue/pieces15176.html

Have 26.13mm, the Numista catalog says must be 25mm. Krause is absent of diameter in this coin. So now I am not sure if mine is real or whatever.

For anyone who have this coin, what is the diammeter of yours?

Thanks for any comment.

Hi, mine is 26,2 mm

I didn't pull out my calipers, but mine is also a tad over 26mm.

The listing for KM# 1 also says 25mm, and based on my coin that appears to be correct. Someone might have assumed they were the same size.
