Reeding

[4] This practice was made more difficult through the implementation of reeding by Isaac Newton in 1698,[6] during his time as warden of the Royal Mint.

This dual purpose of reeding is sometimes made explicit on the milled edges of coins themselves.

For example, many issuances of the British pound coin have historically had their edges inscribed with the Latin phrase 'decus et tutamen', an adaption from Vergilius' Aeneid meaning 'an ornament and a safeguard'.

Its use in this fashion was inspired by Greek and Roman architectural styles,[7] and is the opposite of fluting.

In architecture, reeding is a form of molding usually found on columns, and is sometimes considered to be synonymous with gadrooning.
