This coin was discussed here
https://en.numista.com/forum/topic93590.html#p812105
But as I see nothing was changed in the Catalog yet.
Well, actually the coin that was discussed in that topic was a 10 Rupees... but from Seychelles, not from Mauritius 😉, but the case is similar to the one being discussed here and I'm sure it's the one you're talking about, do not remove the year line that should NOT be there, there are users who use it by mistake.
This is not the first time this has happened at Numista.
The best thing would be to switch users to the correct page and remove the incorrect year line.
