Discovery of a variant for the 4 Soldi of Pascal Paoli

While working on Corsican coins from 1736 to 1768, I came across a very interesting coin. You can see my full work on Corsican coins here: https://www.all-your-coins.com/en/modern-coins/. The discovery is for a 4 Soldi struck under Pascal Paoli.

Having checked in the works, the 4 Soldi is only supposed to have two types: the first visible only in 1762, has two Geniuses framing the crowned head. On the other side ''4_Soldi'' is surrounded by a grènetis (dots). The second type from 1763 until 1767, still shows two mermaids framing the crowned head and ''4_Soldi '' is surrounded by a garland of fairly low quality for the year 1763 and a well suplied and worked crown from 1764 to 1767. Let's look at these two types:

Type 1:

Type 2: 

Mermaids with garland of low quality:

But i discovered this coin from 1763 presenting a garland of low quality, like the normal type for this vintage, but with two Geniuses instead of two Tritons. Here is this coin:

This coin therefore seems very rare, but it would be necessary to analyze more specimens to know its real rarity. To finish, it is funny to see that in the books, we see this same type for 1763 with two geniuses, in photo, whereas it is mentioned only ''mermaids'' ... Error of description? Perhaps, the fact remains that the Triton variant also exists. Both types exist, but this has apparently not yet been noted in the works. Note also that the style of the decor surrounding the head changes from year to year. Many varieties have been listed, without knowing if the variant on this article has already been noted somewhere.
