About Numiis / Numis DB
The numismatic database project is designed to provide all information any coin collector or numismatist would need regarding a coin, medal or note of interest.
A rare coin's potential value is one of the chief determining factors in a collector’s decision to acquire it, as the right rare coin can lead to a future fortune.
There are many complex factors that go into defining a coin’s rarity, and are discussed further in detail here. In the past, determining the potential value of a coin on your own would usually entail doing a lot of research, and knowing where to start has been a daunting task for even the experienced collector. Fortunately, use of the vast Numis DB database makes this task a simple and stress-free process, with the known value of coins from every region and era at a user’s fingertips.
Understanding the traditional process, however, can enlighten collectors as to how these values are determined within the database, as well as give leads as to how they can do their own additional research on coins they want to learn more about. Below, we will explore some of the helpful on- and offline resources that bring insight to a coin’s value.
Rare coins are often bought and sold at auctions, and records of these past sales can often be found online in a variety of places. Learning about a coin’s past performance at different auctions gives a potential buyer some great insight as to the coin’s potential worth, and can also give clues to a coin’s popularity. Numis DB’s advanced technology pools millions of these past auction records together to reach a more exact valuation of a coin based on its past performance, popularity, and market availability, eliminating the collector’s need for guesswork.
Without the need for deep digging, collectors can still use these records to gain more information about current trends, learn about their collection, and help determine other types of coins that they may be interested in. These online sources also tend to have other helpful resources for collectors as well, such as directories of local dealers in your area, and lists of upcoming auctions and events.
Coin dealers and numismatists are excellent sources of information regarding the history and trends of coins and their values. Due to their knowledge and expertise in the coin industry, they can be a helpful guide for collectors with specific questions regarding their coin collection. Dealers may have more firsthand knowledge of coins’ current market value and availability, and in contrast, numismatists may be experts in coins of certain regions or sub-specialties and have a greater depth of historical knowledge to help support their claims. Depending on the coin in question, either may be helpful in providing guidance to determining a coin’s value, and to finding more information about a coin and its history.
Rare coins can be an excellent investment, but predicting which coins will be the most valuable addition to your collection can be tough. Numis DB’s true market values based on hard data relieve the pressure of collectors having to do this research on their own to make their best guess. But having a list of additional reliable resources to refer to when purchasing coins can help a collector be as informed as possible on their investment. Expanding your knowledge in every part of the coin industry will only help you to make smart investment decisions now and in the future.
