In 2020, we commemorate the 500th anniversary of the beginning of the minting of the Jáchymov tolars - probably the most famous Czech coins, whose legacy still lives on in the form of various dollars., The Czech Mint, in cooperation with the Czech National Bank, prepared a luxurious jubilee set of circulation coins minted in top quality proof on this occasion.

Classic circulation coins with nominal values of 1, 2, 5, 10, 20 and 50 CZK, which you encounter daily, are minted in quality "standard". Their entire surface is matte and resistant to damage, which ensures long-life currency. However, Czech metal coins are not just a means of exchange - many people appreciate their artistic processing and therefore include them in their numismatic collections. For these cases, there is a collector's variant of coins in the quality "proof" which is characterized by a mirror-shiny surface and a matte relief. This attractive contrast effect is achieved by a special surface treatment of the tools used for embossing. At the beginning of the "proofing" process, the surface of the entire die is polished using special tools and diamond paste. Then the stamp is covered with a special adhesive tape. On the parts of the relief that are to remain matte, the proofreader will carefully cut and remove the tape. They work under a microscope and apply this procedure to even the finest details. Sand of various roughness is then applied to the camouflaged stamp, which makes the exposed parts of the relief matte. Finally, the remaining tape is removed, which has retained selected parts of the relief polished. Special care is given to the "proof" variant of circulation coins even during the minting itself. It is not an automatic machine minting - each coin is minted individually and packed in a protective capsule.

In addition to the six circulation coins with the year 2020, the set also includes a replica of the Jáchymov tolar made of pure silver. This mintage, made by the academic sculptor Jan Lukáš, presents a two-tailed Czech lion, the figure of St. Jáchym and the coat of arms of the noble Šlik family. In order for the replica to resemble the historical model as much as possible, it is, unlike circulating coins, embossed in quality standard.

The set is supplemented with a numbered certificate of authenticity, produced by the State Printing House of Securities, and stored in an elegant wooden case.
