There was no mention of “Sana”/" Sanna" in your inquiry or even a link. Please be specific in the future.
Large Sanna Different date but for comparison


Trying to find a small Sana for comparison as you can see there is no graphic to it on the Numista page. It is significantly and visually very easy to see once you can find a small example. Will work on it.
I will add that there are untold minor varieties on these type coins and to list every possible variety or provide a graphic, the page would read like an encyclopedia.
