FAQ

What is numismatics?

Numismatics is primarily a scientific discipline that studies coins and other means of payment. When examining coins, it is necessary to analyze information about their historical development, material composition, production techniques, iconography, and economic significance. In this way, numismatics provides valuable insights into the political, cultural, and historical events that occurred even in our region. However, numismatics has also been a hobby for centuries in the form of coin collecting. Collecting coins offers enthusiasts new opportunities and perspectives for exploring the history of our region, in addition to owning fascinating treasures and unique pieces.

Coin Price Lists – How to Determine the Value and Rarity of Coins?

Coin price lists provide a detailed overview of the values and rarities of individual coins. They include information on face values, minting years, mintage quantities, and indicative market prices. For collectors and investors, we recommend using the latest “Catalog of Coins and Medals of Czechoslovakia, the Czech Republic, and the Slovak Republic”, which we update regularly. This catalog includes coin prices from the period of the First Czechoslovak Republic (1918–1938) up to the current Czech and Slovak Republics (including replicas and re-strikes). Prices in the catalog are determined based on the current situation in the numismatic market. However, we advise consulting with an expert before buying or selling coins. Don’t hesitate to contact a trusted partner who can provide valuable advice and professional support.

What is the value of historical (collectible) gold coins?

Historical (collectible) gold coins hold significant cultural, historical, and investment value. These include ducat issues and their multiples from mints in the Czech and Slovak territories during the Habsburg reign, Celtic coins minted in our region, or ducats issued during the Czechoslovak Republic. These coins were crafted from high-quality gold and often feature artistic motifs reflecting the era of their production. Their value depends on factors such as historical significance, condition, rarity, and market demand. When investing in historical coins, it is essential to verify their authenticity, condition, and provenance. With us, you can be confident in all these aspects – we provide a lifetime guarantee of authenticity for the coins we sell, and each coin is assessed by our experts based on years of experience and thorough multiple checks. Historical (collectible) gold coins are not only beautiful objects but also an intriguing tool for diversifying investment portfolios and connecting with the past.

Where to sell rare coins? Where to sell a coin collection in Slovakia and the Czech Republic?

For selling rare coins, it is advisable to contact specialized numismatic shops and auction houses. We believe we are the right partner for selling your collection, as we have handled the sales of some of the largest Czech collections or their parts, such as the collections of Dr. MUDr. Bruna, Novák, Ing. Kokolus, and smaller estates of extremely rare coins, such as those of Dr. JUDr. Zedwitz, who received coins from President Edvard Beneš. Before including items in an auction, we expertly assess their suitability and authenticity, and then offer them in our regular in-room or e-live auctions, which we hold twice a year.

Investing in Gold Coins – A Beginner's Guide or Which Gold Coins to Buy?

Investing in gold coins is a popular way to preserve value across generations. For beginners, it is advisable to focus on well-documented periods, as these offer basic literature that helps new collectors familiarize themselves with the area they wish to explore. At the start, it’s a good idea to consult experts about how to begin collecting historical coins. The first step is to gain an overview of the auction market where collectors operate. Then, identify the periods and coins that appeal to you. After selecting a period, it is beneficial to seek advice from experienced collectors about its suitability for building a collection. Experienced collectors can provide valuable insights, such as the usual price ranges, the availability of specific denominations for particular rulers, and other essential facts. These details significantly influence the process of collecting and the ability to create comprehensive sets of coins.

How to Identify a Gold Coin?

Determining the authenticity of a gold coin can be done using several methods. The first step is to check the hallmark, which indicates the gold’s purity and is typically stamped on the coin's surface. Another method is the magnetic test, as gold is not magnetic; if the coin is attracted to a magnet, it likely contains other metals. Another option is density measurement: gold has a high density, so comparing the coin’s weight and volume can reveal any inconsistencies. For precise verification, it is recommended to consult an expert or use specialized equipment like an XRF spectrometer.

How to Determine the Value of Old Coins?

The value of coins depends on several factors. Purity and material play a crucial role, particularly the content of precious metals such as gold or silver. The condition of the coin is also essential – undamaged and well-preserved coins generally have a higher value. The year of minting and mintage are additional key factors, as older coins or those minted in limited quantities tend to be rarer. Lastly, historical and collectible significance can greatly influence value, especially if the coin is associated with significant events or personalities. For an accurate valuation, it is recommended to consult a coin catalog with prices and seek advice from experts.

What Are the Most Common Numismatic Abbreviations and Their Meanings?

In numismatics, many abbreviations are used to describe the condition, rarity, and other characteristics of coins. For describing condition, designations such as UNC (uncirculated/stgl.) are commonly used, indicating that the coin has not been in circulation and is in excellent condition. Other grades include about UNC (fast stgl.), good EF (vz+), EF (vz), about EF (f. vz), good VF (ss+), VF (ss), about VF (f. ss), and F (s). These labels help determine the degree of wear on a coin. Rarity descriptions include abbreviations such as R (rare), RR (very rare), RRR (extremely rare), and the term Unique, which means there is only one piece on the market. These abbreviations provide collectors and dealers with a quick overview of a coin's condition, rarity, and value, making it easier to assess and trade coins.

How to Clean Coins and What Is the Best Way to Clean Them?

Cleaning coins is a delicate process that can impact their value, often in a negative way. Generally, it is advised not to clean coins, especially historical or collectible pieces, as improper cleaning can cause irreversible surface damage and reduce their value. In some cases, people mistake patina for dirt or fail to recognize certain imperfections as natural reactions of the metals and trace elements present in the coins. In cases of severe dirt or contamination, it is best to consult an expert or numismatist. They can recommend an appropriate cleaning method that avoids the risk of damaging the coin.

How to Identify Counterfeit Coins?

Identifying counterfeit coins requires a thorough examination of several key aspects. The first step is a detailed inspection, comparing the coin’s details with official designs. Counterfeits often exhibit inaccuracies in relief or text. It is also important to verify the material and weight of the coin – dimensions and weight must match the original. A magnetic test is another useful method, as genuine gold and silver coins are not magnetic. Some coins may include specific security features, such as microtext or special minting, which help verify their authenticity. For complete certainty, we recommend consulting an expert to evaluate the coin’s authenticity reliably.

How to Determine the Value of Old Banknotes?

The value of banknotes, similar to coins, depends on several factors. The key aspects are the condition and preservation of the banknotes. It is especially important to determine whether the banknote has been altered, such as through repair or ironing. Altered banknotes are significantly less valuable than unmodified ones. Another crucial factor is the series of the banknote, as there is often a significant difference in value between regular and replacement series. The perforation of the banknote is also an important consideration. Generally, unperforated banknotes are more valuable than perforated ones, with the exception of so-called bank patterns, which are rare and highly popular among collectors. To accurately determine the value of a banknote, it is advisable to consult a catalog of banknotes and seek expert advice.

How to Identify Counterfeit Banknotes?

Identifying counterfeit banknotes requires a thorough examination of several aspects. The first step is a detailed inspection, comparing the banknote’s details and security features. Counterfeits often show differences in the paper quality, as it is challenging to replicate historical paper in modern times. You may also encounter fake perforations on banknotes. This means the banknote itself is genuine, but the perforation is not original and does not come from official bank perforation machines. For complete certainty, we recommend consulting an expert who can provide a reliable assessment of the banknote’s authenticity.

What Is the Difference Between a Coin and a Medal?

One of the most common questions we encounter is the difference between a coin and a medal. The primary distinction is that a coin is intended for payment – it has a face value and can only be issued by the national bank of a country or a group of countries where it is legal tender. On the other hand, a medal is not intended for payment. It primarily serves as a commemorative piece for significant personalities or events. Medals can be commissioned by anyone for any occasion – whether an individual, a company, or an institution.

What is grading?

Grading is the process of verifying the authenticity and assessing the condition of collectible coins, medals, or banknotes, which includes encapsulating them in a protective holder known as a "slab." This procedure is carried out by independent experts who evaluate the item's authenticity and quality based on internationally recognized standards. Each certified item is assigned a unique identification number that allows verification of its authenticity and condition in online databases. Grading enhances the credibility and market value of collectible items by providing a guarantee of their authenticity and quality.
