NEPAL KM#742 listing error?

I have KM #740, the 1/2 Rupee version of #742, and it matches the Numista data for that coin: 25mm and 6 grams. I also have #743, another 1 Rupee version of #742, and mine matches Numista: 28.7 mm and 11.7 grams.

I don't have #742, but it seems to me that the Numista data here is incorrect (based on my attempt to acquire it). I know that #742 is a 1 Rupee coin. But can it really be 25mm and 11.5 grams?

Does anyone have this coin (#742) to check?

#740: Rs. 0.5, 25.0 mm, 6 gr.
#742: Rs. 1.0, 25.0 mm, 11.5 gr.
#744: Rs. 1.0, 28.7 mm, 11.7 gr.

Thank you. Thank you.
