Hi Young,
It is a
billon denaro of
Sicily from the fifteenth century, when ruled by Aragonese kings. The
obverse is an
eagle with the rulers name in
legend around. I cannot make out the
obverse lettering, but for
Martin I or II (1402-1410) it would be :plus:
MARTIN:D GR. For Alfonso the Magnanimous (1442-1458), it would be :plus:ALFONS:D:GR. For
John II (1458-1479), it would be :plus:IOANNES:D G. For Ferdinand the Catholic (1479-1516), it would be :plus:FERNANDVS D G. The
reverse is the
shield of Aragon with the
legend :plus:
REX:SICILIE or similar. I do not notice any
mint master's initials on the
reverse, so I would think that your coin would be from the Martins or Alfonso's reign.
Mint master initials can be above or either
side of the
shield on the
reverse.
Mint would be Messina. I gather this information from
Medieval European Coinage 14.
Hope this gets you in the right direction.
Cheers,
David
