How do I request a year be added for a coin? [Risolto]

I have a 1 Duit I inherited from my father in-law and it's year is missing from the page on the Numista site. How do I request the year be added? Here is a picture of the coin I have:


The years listed on the site are:
1768, 1769, 1770, 1787, 1788
Thank you!

What page were you looking on? It is here, with many other dates ...

Although - maybe you were looking at this (silver) page ...

Yours looks like copper.

Thank you so much! That is it! The page you gave a link to didn't show in my search. Many thanks!
