we see here a SHIELD of a KING, which carries a SIX-POINTED STAR only this king, here, is a Roman king (Augustus 17 BCE). I guess that Jews actually held these coins in their hands after the first century B.C.E (so close to the destruction of the temple in 70 C.E ) and this material image may have triggered the invention of King David's Shield. Anyhow I’m sure that you’ll be surprised from this coincidence at least as I was when I stumbled upon these pictures.
King with shield or Goddess of Victory with shield on Roman coins is a frequent motif.
See coin with shield with Double Square (two squares inposed on each other with a shared center like the six pointed star having two triangles arranged similarly)
