What is the difference between Piedfort and Standard?
Updated in June 2026: We have reviewed this article and added information on Piedfort coins, standard proof coins, and the main differences for collectors.
In short:
Piedfort coins differ from standard coins primarily in their greater thickness and weight. This article explains what Piedfort means, how such issues differ from standard proof coins, and why they may be of interest to collectors of modern gold coins.
In the world of numismatics, there are pieces that immediately catch the eye – not because of their diameter, but because of their massive presence. We’re talking about Piedfort coins . But what exactly distinguishes a Piedfort from a standard proof coin, and why are they so sought after by investors?
At Wasserthal RareCoin.Store, we analyze the subtle differences that can multiply the value of your collection.
What is a Piedfort coin? A definition
A piedfort coin (also piéfort ) is a coin distinguished by its exceptional thickness. These coins are typically twice as thick and twice as heavy as standard issues of the same denomination and design.
It’s important to know that piedforts were never intended for everyday use. They are purely collector’s items or display pieces, prized for their rarity and impressive feel.
Etymology and pronunciation
The term originates from French:
-
“pied” (foot)
-
“fort” (strong, large, heavy) Literally translated it means “strong foot”, which in a figurative sense stands for “heavy weight” .
-
Pronunciation: [pjefɔʁ] (French) or “Pie-for”.
Piedfort vs. Proof: The main differences at a glance
Many collectors confuse the terms, even though they describe different characteristics. While “proof” (polished plate) describes the stamping process , “piedfort” refers to the physical quality of the blank.
1. The thickness
The most striking feature: When a piedfort is placed next to a standard coin, the standard coin appears almost delicate. The piedfort utilizes vertical space, giving it a solid, almost medal-like appearance.
2. The weight
Since piedforts are usually exactly twice as thick, the weight of the precious metal (e.g., gold or silver) is also doubled. This makes them particularly attractive to investors seeking compact yet heavy tangible assets.
3. The manufacturing process
The embossing of a piedfort requires significantly higher pressure and special tools to press the metal into the high relief edges of the thick blank. This often results in even sharper detail than with standard embossing.
Historical significance: Diplomacy in precious metals
Piedforts were originally minted in 12th-century France and England as masterpieces for coin engravers or as diplomatic gifts for kings and nobles. They were symbols of wealth and technological superiority.
A fascinating modern example is the Uruguayan coin of 1983 (20,000 Nuevos Pesos) commemorating the visit of the Spanish royal family. Both the standard proof version and the extremely rare Piedfort variant exist side by side – a perfect study object for numismatists.
Why are Piedfort coins so valuable?
-
Extreme rarity: Piedfort print runs are often only a fraction of standard proof print runs (often only a few hundred copies worldwide).
-
High material value: Due to their double weight, they automatically contain more gold or silver.
-
Prestige: In a collection, Piedforts are like the “crown jewels”. They are both a topic of conversation and a valuable investment.
Conclusion: The crowning achievement of any collection
Although both standard proof and Piedfort coins have their appeal, the Piedfort offers an additional dimension of exclusivity. Its rarity and historical connection to the royal houses of Europe make it a must-have for serious numismatists.

Frequently asked questions about Piedfort coins
How does a Piedfort coin differ visually from a standard coin?
At first glance, the two versions often look very similar, as the design and diameter are identical. The difference lies in the thickness: A piedfort coin is usually about twice as thick and correspondingly heavier than the standard version.
Is a Piedfort coin an investment coin or a collector’s coin?
Piedfort coins are primarily valued as collector’s items, but due to their double thickness, they also contain twice the precious metal content of the standard issue. This makes them attractive to both specialized collectors and investors who want to combine intrinsic value with rarity.
Are Piedfort coins rarer than Proof coins?
Piedfort issues are usually minted in significantly smaller runs than regular proof coins of the same design, making them a particularly sought-after variant for specialized collections.
How can I recognize a genuine, certified Piedfort coin?
The most reliable way is through an independent certification by NGC or PCGS, which documents the weight, dimensions and authenticity of the coin and provides a traceable certification number.
Is a Piedfort coin worthwhile for beginners in numismatics?
Piedfort coins are well suited for collectors who already have a basic understanding of standard coins and want to specifically invest in rarer, thematically related variants.
