queries on the weight and diameter

Dear all,

Is the weight listed in the following correct ?

https://en.numista.com/catalogue/pieces47758.html

It shows weight 18.4g and diameter 38mm.

However it shows weight as 28.28g and diameter as 38.60mm in this site:

Can anyone advise ?

Thanks.

Hi,

I think there is an error on the Numista card.
All of these coins weight 28.28g.

Thanks so much for the clarification :)
