About Wasserthal RareCoin.Store – Experts for certified numismatic gold coins

Certified gold coins are the focus of Wasserthal RareCoin.Store.

Wasserthal RareCoin.Store is your specialist partner for certified numismatic gold coins from 1950 onwards . As a brand of TriaPrima GmbH , we focus on rare collector’s items with documented rarity, a clear valuation basis, and international recognition by NGC and PCGS .

We deliberately differentiate ourselves from pure bullion trading. Our focus is on carefully selected gold coins, where not only the metal value, but above all the grade of preservation, population, and global market relevance are paramount. For discerning collectors, we thus create access to values ​​that extend far beyond the pure gold price.


Our specialization: Quality over quantity

Wasserthal RareCoin.Store stands for in-depth expertise in modern gold numismatics. Our product range focuses particularly on:

  • Proof gold coins (referred to as “polished plate” in German-speaking countries) of the highest minting quality.

  • NGC and PCGS certified gold coins (slabbed coins).

  • Strictly limited editions with top populations (low stock numbers in the respective grade).

  • Modern commemorative editions and internationally sought-after series.

The focus is on icons such as the Krugerrand Proof , the Mexican Libertad , as well as the Natura , Big Five , American Eagle Proof , and Canadian Maple Leaf Proof series. These issues combine aesthetic perfection with documented rarity, making them highly relevant to the international collector market.


Our philosophy: What matters in a valuable collector’s coin

In a market that often seems difficult to understand, we rely on three clear pillars that make the difference between an ordinary gold coin and a true numismatic rarity:

1. Focus on modern relevance (from 1950 onwards)

We focus on modern issues such as the Maple Leaf Proof , the Mexican Libertad , and the South African Krugerrand. The reason: These coins offer a level of transparency, thanks to precisely documented mintages and state-of-the-art minting processes, that ancient coins often lack. The Proof version, in particular, represents a rarity that combines numismatic excellence with lasting value.

2. Objective quality through certification (NGC & PCGS)

A coin is only as valuable as its verifiable condition. That’s why we consistently rely on certification by NGC and PCGS . A sealed holder (slab) not only guarantees authenticity but also fixes the grade of preservation on an internationally recognized scale – a crucial factor for worldwide tradability and your security when reselling.

3. The importance of rarity (top population)

The value of a coin depends not only on its total mintage, but also on its population . This describes how many coins exist worldwide in perfect condition (e.g., MS70 or PF70). We specifically search for coins with a top population , as these flawless specimens represent exclusive rarities, even within well-known series.
