A complete pattern showed that the edge was intact.
Machine striking produced thicker, more uniform coins. The Mint could then add grooves, called milling or reeding, or an inscription around the edge. That pattern ran around the full rim. Shaving the edge removed part of it, making the cut obvious.
Some coins carried Decus et Tutamen, Latin for 'an ornament and a safeguard'. The words described the edge itself: decoration that also revealed tampering. Old hammered coins kept circulating, so clipping remained a national problem until the Great Recoinage of the 1690s.
William III taxed windows to replace revenue lost to coin clipping.
