Our service for rare coins begins with a professionally sound appraisal. Buying or selling a rare coin requires more than just comparing its weight and precious metal price. Year of issue, mintage, minting quality, condition, certification, population, and current market availability can all be crucial for its numismatic classification.
Wasserthal RareCoin.Store specializes in modern numismatic gold and platinum coins from around 1950 onwards. The focus is on rare proof issues, low mintages, top-pop and low-pop issues, as well as internationally recognized certifications from NGC, PCGS and CAC .
Our service is aimed at collectors, buyers, and sellers who desire a personal and transparent appraisal. Inquiries are not processed automatically or anonymously, but are individually reviewed.
Service for rare coins – Personal consultation when buying rare coins
Rare coins are not standardized products. Even two specimens of the same issue can differ significantly in their condition, certification, or position within the known population.
Before you make a purchase, we can assist you with questions about:
- Year of issue, country of issue and mint
- Edition and documented rarity
- Proof, reverse proof and mint state outputs
- NGC, PCGS and CAC certifications
- Preservation grades such as PF70, PR70 or MS70
- Top pop and low pop editions
- Original packaging and certificates
- known populations and market availability
- the classification of the offered price
We clearly distinguish between verifiable characteristics of a coin and mere marketing claims. A low mintage alone does not automatically make an issue rare, just as a high degree of preservation does not guarantee a specific future value.
Support in the targeted development of a collection
Many collectors do not focus on just any individual piece, but on a specific country, mint, series, year range, or a particular minting quality.
We can help you narrow down your collecting area and identify suitable coins. The following criteria, among others, can be taken into account:
- Country of issue or mint
- Motif, series or historical context
- Metal and weight
- Embossing quality
- desired degree of preservation
- Certification by NGC , PCGS or CAC
- known population
- available budget
Our goal is not to recommend as many coins as possible. What matters is whether a piece fits your existing collecting area in terms of expertise, quality, and price.
Searching specifically for rare coins
Not every rare coin is available at all times. Certain years, proof issues, or particularly highly valued specimens only appear irregularly on the international market.
If a coin you are looking for is not currently in our inventory, you can place a search request with us for specific years, grades, or series. The more precise your information, the more effectively we can check whether a suitable specimen is available.
The following are particularly helpful:
- Country and year of birth
- Series or exact designation
- Metal and weight
- desired embossing quality
- preferred state of preservation
- desired grading company
- Certification number, if a specific copy is already known.
- approximate price range
We draw on our international network of dealers and collectors. However, successful procurement of exceptionally rare coins cannot be guaranteed.
Correctly classifying certifications and populations
Certification by NGC, PCGS, or CAC confirms important characteristics such as authenticity and condition. It also facilitates international comparison and can improve a coin’s future marketability.
However, the label alone does not answer every question. For a sound classification, the exact variant, the minting date, the minting quality, and the published population must also be considered.
Top Pop coins deserve special attention. Within their respective valuation groups, they are among the highest-rated known examples. Nevertheless, the following should be checked:
- To which specific variant does the population refer?
- How many coins of the same grade exist
- Are there any known higher-rated specimens?
- How frequently the edition is actually offered on the market
- Whether signatures, special labels or packaging are recorded separately in the population.
We help you to professionally classify certification data and population reports.
Evaluate and sell coins
Do you want to sell individual coins or a collection ? For an initial assessment, you can send us informative photos and the available information digitally.
The following are particularly helpful:
- Clearly recognizable photos of the front and back
- Images of the packaging or the slab
- Certification numbers
- Information on year, weight and metal
- existing invoices or certificates
- an overview of several coins
Based on this, we first check whether the offered coins fit our specialization and current purchasing activities. We cannot accept every coin or every collection.
For the valuation, we consider not only the precious metal value. Depending on the issue, condition, mintage, population, demand, certification, and international market availability can also play a significant role.
A final appraisal and a binding purchase offer are only possible after examination of the original items. The exact procedure, insured transport, and further process will be agreed upon transparently in advance.
Secure ordering and fully insured shipping
For high-quality coins, transparent payment processing and suitable shipping are particularly important.
Orders can be paid via bank transfer or PayPal. Available payment methods may vary depending on the destination country and the specific order.
Shipping is handled by suitable shipping providers, depending on the value of the goods, the delivery address, and the destination country. Every shipment is fully insured until it is personally handed over to the recipient or an authorized person.
After shipment, you will receive the shipment details and, if available, a tracking link. For deliveries outside the European Union, product- and country-specific restrictions may apply.
Transparent classification instead of value proposition
The value of a rare coin can be composed of several components:
- precious metal value
- numismatic rarity
- State of preservation
- Certification
- Collector demand
- international market availability
These factors can change over time. Therefore, we do not make any general promises of returns or guarantees of future increases in value.
A rare coin should be judged based on its specific characteristics. Simply pointing to a low mintage, a special design, or a high degree of preservation is not sufficient.
