These are really neat old silver coins. Some are very valuable, others are not. The basic pattern is the Jerusalem Cross on one side with the words IN HOC SIGNO VINCES (in this sign you will conquer) and a crowned shield on the other side with the name of a Portugese ruler and some form of PORT ET ALG (Portugal and Algarve; Algarve is the southern region of Portugual) REX (king). The denomination is keyed to size, with 200 reis and 400 reis called out explicitly. Sometimes there is no date.
60 REIS, 1667 to 1777: about 18 mm diameter
120 REIS, 1667 to 1816: about 24 mm
200 REIS, 1677 to 1816: about 28 mm
400 REIS, 1681 to 1816: about 36 mm
The beautiful coin in our picture comes from Chris'Numismatique in Ennery, France. It is on sale for 80 euros (about $100 US dollars), which is a good price for such a nice looking specimen. CoinQuest thanks Chris'Numismatique for use of their coin image.
The rulers names that appear on these coinsare:
PETRVS II: Peter II, 1667 to 1706
IOANNES V: John (Joao) V, 1706 to 1750
JOSEPHUS: Jose (Joseph), 1750 to 1777
MARIA I ET PETRUS III: Maria I and Pedro III, 1777 to 1786
MARIA I: Maria I, 1786 to 1759
JOANNES P REGENS: Joao, 1799 to 1816
(Note to Philbert: You did not give us much to go on, and this is our best guess at your coin. Note that a JOSEPHUS inscription is not consistent with your 1778 date. If your coin has both JOSEPHUS and 1778, please contact CoinQuest for further investigation.)
We can give a general idea of value of these on this page, but if you have a nice looking coin you should probably contact a knowledgeable coin dealer or coin collector for an in-person evaluation. There are subtle differences in these coins and sometimes the differences create quite a swing in value. We identify a few such swings below, but not all of them.
