Hi Nassif,
Chios is not in Europe. It is an island off the
west coast of
Turkey, in the eastern Aegean Sea. During the late Middle Ages, it was a colony of the Genoese Empire. They may have "acquired" it from the Venetians. Most colonies of the Genoese Empire were former colonies of the Venetian Empire. During the Crusades, the
Christian Crusaders from Europe, many of whom launched from Genoa, used
Chios and other islands in the eastern Aegean Sea as hopping points or resting points (to look over the booty that they stole from the Middle East, etc.).
"La Maona" is the name of a company formed by the Genoese. Its primary function was to forcibly extract
money (taxes, tribute, etc.) from the
colonists in
Chios and elsewhere. It was similar to the modern-day
Italian mafia, who forcibly extract "protection
money" from people. La Maona were not nice people. They often severely beat people up when they didn't "pay up" (just like the modern-day
Italian mafia).
The reason you didn't see this coin in any sales or
auctions is because it is very
rare (at least a R2, possibly a R3). If possible, try to see if you can look at some old
Italian auction catalogs (Varesi, Artemide, etc.) for coins of this
type. Every now and then, they will sell one of these coins or a similar one. In particular, Varesi
had an
auction in circa 1999-2001 with hundreds of Genoese coins. I remember that
auction because I was the winning bidder on numerous Genoese coins. If possible, see if you can look at it (online?). There are probably a few examples of this coin
type in that
auction. As you may know, I love Genoese coins because my paternal grandparents came from Genoa,
Italy.
