Matthew 22:20

Image and superscription [ε ι κ ω ν κ α ι ε π ι γ ρ α φ η]. Images on coins were not approved by the Jews. Out of respect to this prejudice none of the earlier Herods had his own image impressed on them. Herod Agrippa 1, who murdered James and imprisoned Peter, introduced the practice. The coin shown to Christ must either have been struck in Rome, or else was one of the Tetrarch Philip, who was the first to introduce the image of Caesar on strictly Jewish coins.
