at Lisbon is a pattern of one with the name of Pedro II.;
ordered and withdrawn, as no such coin is known.
it was perhaps
Constantin, the name applied to the gold money of Louis Constantin
De Rohan, Bishop of Strasburgh, i8th c.
*Conto, Portuguese computation, 1000 millreis.
Convention-money, a principle, analogous to that of certain states of
ancient Greece, by which a currency was tolerated or recognised within
a stipulated radius at a fixed standard. The practice does not seem to
have come into vogue in the Low Countries till the I4th c. (see Drielander*
Jager, Rozenbeker, and Vierlander). The earliest trace of this sort of
treaty was, we believe, in the monetary arrangement in 1240 between
the town of Lindau, Bavaria, the Bishop of Costanz, and others. This
was long prior to that between John I., Count of Namur (1297-1331), the
Count of Flanders, and the Duke of Gueldres ;
and we are not to forget
the somewhat later compact of Edward III. of England (1345) with the
Emperor Louis of Bavaria and the Duke of Brabant at a time when the
extension of English commerce and coinage rendered such facilities of
peculiar importance to that country. There are very curious types of
1479 for Daventer, Campen, and Groningen, and of 1488 for Daventer,
Campen, and Zwolle ;
the latter convention appears to have been still in
force in 1588. A proof \ daalder on a square flan, and daalders of 1584
and 1588, with the titles of the Emperor Rudolph II., were struck for the
three towns in common. The majority of the German princes, both lay
and ecclesiastical, used convention-money during the i8th and even
igth c.
Coquibus, a denomination in silver of the Bishops of Cambrai, I3th-
I4th c.,
and also current in the diocese of Metz and in the Netherlands.
The name is said to have been a popular sobriquet, occasioned by the
eagle on the piece being mistaken by the common people for a cock a
not improbable error, as that bird is frequently delineated on coins of all
ages in such a manner as to be mistaken for a pigeon or a sparrow.
Cornabo, a silver coin of the marquisate of Saluzzo, I5th-i6th c.
Cornado, a billon coin of the ancient kingdom of Castile and Leon,
1
3th c.
Coroa de prata, a piece of 1000 reis, struck under Maria II. of Portugal
(1837).
Coronato, a silver coin of low standard of Ferdinand I. of Arragon,
King of the Two Sicilies, 1458-94, so called from the legend Coronatvs
:
Qu\f\a Legitime Certavi. There are at least two types of this, and one of
the following reign, that of Alfonso II., 1494-95. Of those of Ferdinand,
one has on obv. the portrait, and on rev. a cross ;
the other has on rev.
St. George and the Dragon, and behind the bust on obv. T. for Trinacria.
The Alfonso coin has the St. George reverse with the Z and on the
.,
other side the ceremony of coronation as in the engraving. The type of
the coronato struck by Ferdinand, probably the latest one, has the portrait
on obv., and the St. George and Dragon on rev. Behind the bust occurs
T. for Trinacria, as on some of the money of the Norman Kings of
Sicily.
*Coronilla, Spanish gold.
Vientin D'Oro, value 20 reals.
Coronnat, a name officially applied, from a large crown in the field,
to a type struck at Marseilles in and after 1186 by the Counts of Provence,
Kings of Arragon, and Counts of Toulouse. The piece, of which
six went to the gros d'argent in 1230, occurs in a document of 1186 as
Novus Regalis Coronatus, or Regalis Massilie Coronatus j it may probably
