Etymology
From Old English hreod.

Usage
"Historically, these three coins were made out of precious metals such as silver or gold and were worth their weight in that metal. People thought they could get more for their money if they shaved a little off the sides and kept the shavings for future use. So, the Mint added the grooves or reeding to prevent cheating." — Kristina Lanier; At The US Mint They're Making Change; The Christian Science Monitor; Jul 7, 1998.
