Countermarks
The four and two Tari coins normally minted in silver were made in copper due to the depleted Treasury of the order. All of these coins have the inscription 'Non Aes Sed Fides' (Not Copper but Trust). The countermarking of these coins started during the reign of Jean-Paul Lascaris Castellar (1636 - 1657) because of the counterfeiting both within Malta and abroad. There are eight different countermarks.
| Jean-Paul Lascaris 1636 - 1657 | Double-Head Eagle (within a circle or shield) |   |
| Rafael Cotoner 1660 -1663 | Head of John the Baptist |  |
| Adrien de Wignacourt 1690 -1697 | Crowned Fleur-De-Lys |  |
| Ramon Despuig 1736 -1741 | Crowned Star |  |
| Emmanuel Pinto 1741 - 1773 (two) | Crowned Crescent & Monogram M A |   |
| Emmanuel de Rohan 1775 - 1797 (two) | Crowned Mascle & Paschal Lamb |   |
