Assistance With New Acquisition: 1794 Ragusa Libertina

My bad, did not check user settings after creating my profile.

Should be OK now, but since you answered here already I'll send you the part about Libertina later today.

As a side note and a comment to your opening post, Libertinas are usually one of the best struck coins of the Republic in circulation.
It is, by historical denomination, the most valuable coin in the entire numismatic Panteon of the Republic, with the original value of full two Ducats.
Therefore it was probably physically exchanged very rarely and kept in safe places most of the time.
There have been accounts/sightings (by Mr. Resetar who provides a large amount of canon literature on the subject) of golden Libertinas in circulation - such a coin, if proven original, would be worth a fortune (caveat emptor!).
Your Libertina seems to have been through quite a lot and could have an archeological root, rather then typical "hauled away en masse from public and private stashes during Austrian rule" history.

Unfortunately, the amount of information about Libertina in the book I have with me right now (Mimica: Numismatik auf dem historischen Boden Kroatiens) was disappointing.
I guess I have to dig up the one from Mr. Resetar (Dubrovacka numizmatika I i II), which might take a while since I have no idea where it is.

This is what I have from Mimica:

Weight 28.887g, 601-603/1000 silver content, radius 41.5mm.
Minted from 1791. to 1795.
Value of the coin was 2 Ducats or 80 Dinaric.
Avers portraits the bust of Maria Theresia (a very popular motif at the time) facing right and the inscription "Respubl Rhacus"(Republic of Ragusa).
Revers displays the coat of arms of the Rector and inscription Duce Deo Fide et Ivist"(under the guidance of god, faith and justice), with the year and initials of the caster Giovanni Angeli (also der Gießer).
Two laurel branches are surrounding the coat of arms.
The coin was minted in a ring, hence perfect dimensions and ornamental edge.
The coin was also used after the fall of the Republic (1808), until 31.8.1817., when it was banned by Austria as illegal tender.
Overall, the mint of the Republic of Ragusa was working between 1337. and 1803.

Here are the ratios between the nominal values of different types of Ragusian coins, with Libertina being on the top: https://hr.wikipedia.org/wiki/Dubro...4%8Dki_novac

This is from Resetar's book:

Libertina was originally made to be popular with the Ottomans, since the coins with the motif of Maria Theresia were getting more numerous and popular.
In the year 1786 it was concluded that the old Talers from Ragusa looked too crude and the plans for creation of Libertina were set in motion.
There is decision of the Senat from 24.10.1792., in which a person named Curic was instructed to bribe the appropriate instance in Istanbul (with up to 1000 Ducats) in order to achieve the exchange rate of 85 Dinaric for one Libertina.
At any rate, it seems certain that Libertina was used extensively between Ragusa and the Ottomans.

I agree with the above information. My coin is 28.85 grams,41.4-41.7 mm in diameter. It is very round in comparison with the crown-size coins of the same era. I had also measure its S.G.9.813, is equivalent to 56.9% silver.
The pictures below.

The awkward 4 does seem interesting.
I do not have it, but several other years (like 3 and 5) also have an odd-looking last digit.
Perhaps Mr. Angeli was being creative with his casts.
Are you collecting Ragusa?

Just asking since it is my only significant collection, always hoping to find fellow enthusiasts.
Today's Ragusa/Dubrovnik is a quite beautiful city, there are lots of places named after it around Europe too.

Here is a low-res revers, uploaded directly to this site.
Please note that the coin edges are artificially cropped / there is a circle layer superimposed on the outer ring.
