Unique and unknown: the story behind the 10 most valuable antique coins in the world

Have you heard of Numismatics?

Numismatics, a term that designates the study and collection of coins, stamps and paper money issued by a nation with the official design of the country. When dealing only with paper money, the term Notaphily is usually preferred. Numismatics has been known since the time of the Persian Empire, although it is not possible to know for sure when it began as a social phenomenon (collectors). Numismatics as a science timidly began in the 19th century, a time of modernization and appreciation as such of all sciences, as we understand them today.

Cataloguing according to conservation

It should be noted that this classification is subject to changes in valuation according to the historical circumstances surrounding the minting of the coins (and other effects of similar function). Thus, we find coins that are very badly treated or have manufacturing defects, which, because they are scarce or even because of those defects, achieve a much higher value.7


Uncirculated (S/C): pieces that have not had much circulation in the market, but have been destined for it. They have no defects.
Excellent good conservation (EBC): it does not have imperfections appreciable at first sight, but it contains the typical traces of a brief circulation and some small blows .
Very good conservation (MBC): good conservation, but has clearly been in progress and has more blows and even scratches .
Good conservation (BC): its numismatic value is half that of the BC. Circulation and imperfections are evident and marked .
Regular conservation (RC): it has scratches, dents, worn out reliefs and other damages of this nature.
Bad conservation (MC): its legends and drawings are illegible or practically unreadable. The metal no longer shines and the imperfections are large: cracks, large dents, erosion of the edge, broken or rusty parts etc.
When a coin is between two categories, it is indicated by a slash or a slash, for example: EBC/MBC. The + or – symbols are added. – after a category to indicate intermediate characters.
