Piedfort Coin

Piedfort Coin, what does it mean?

If you are a fan of coin collecting you may have come across coins described as Piedfort Coins. See Piedfort coins for sale.

The Piedfort Coin dates back to the Middle Ages and refers to a coin struck double thickness of the regular coin. The diameter will be the same and it will have been stuck with the same mint dies as the standard coin.

Piedfort – double thickness coin

They originated in France (hence the French name) and were issued as sample coins to demonstrate new coin designs. 

Britain stopped producing Piedforts way back in the sixteenth century, the last example being a sixpence struck in 1588.

Piedfort Definition

Simply put, a double-thickness coin; made to proof quality for coin collectors

These special coins were given the name ‘Piedfort’ meaning ‘heavy measure’ (literally “Heavy Foot” in French). You may also find these coins referred to as the ‘Piefort’ coin, this is a misspelling.

Another error is in the thinking that this term relates to the weight (not thickness) of a coin. Although of course, a double-thickness coin is also double the weight!


You may hear many different ways to pronounce the term “Piedfort”, especially different between British English and American English.

The most common is pee-ay-fore – as is typical in the French language, the “T” at the end is silent.

The Oxford English Dictionary version is pjeɪfɔːt, see their page for an audio clip to listen to.

Coins fit for a King!

Piedfort Coins were minted as Royal prestige pieces from the mid-16th to the mid-17th century, where Kings and Queens began the tradition of giving ‘prestige pieces’ to members of their court.

Some Kings and noblemen had these extra thick coins struck, either to display or to give as gifts. This was a way of showing wealth and power during these times.

In England, the gold Double-Sovereigns of Henry VI were one spectacular example!
