Unlike the situation at the start of the First Revolt, in Bar Kochba's time there was no Temple and no Temple Treasury. Then they filed off the original designs and restamped them with Jewish symbols and Hebrew inscriptions relating to their hope of rebuilding the Temple.
Many coins exhibit parts of the original designs and legends.
And some of these large silver coins issued in the third year of the revolt feature a wavy line above the Temple, perhaps representing an ornamental grape vine. In a letter from Bar Kochba, discovered in the late 1950s, the Jewish leader orders Judah Ben Manasseh to supply him with lulav for his army so that they could celebrate the festival even though they were in the midst of major battles. There are some very rare Year 1 denarii inscribed Eleazar the Priest instead of Shim'. The symbols are associated with the Temple - palm branch, amphora, bunch of grapes, lyre and trumpets. A file was used to remove the designs of the underlying coins, such as the portrait of the Roman Emperor, and this is readily apparent on some of the large bronzes.
