Authenticity check #3: Victoria shilling 1866 [resuelto]

Hello,
I got this coin a while ago and something feels a tad off...though I can’t quite grasp what it is. The diameter is 24mm, thickness 1mm, weight 5.32g. I don’t think that matches the catalog information, does it? Or is it nothing to worry about?

Nothing seems too off about the dimensions:

100% perfectly fine, if anything I'd be more suspicious if it were in better shape with less wear.

Since it is worn, you expect a slight loss of weight.

Okay! I just felt a tiny bit off about it, for some reason. Thank you!
