The National Bank of Kazakhstan has issued a set of collection coins depicting BALQASH ALABUGASY (Balkhash perch).
The coins are 3D and the ultra-high relief technology has been used for their production.
According to the information available at the website of the National Bank of Kazakhstan, these are the only 3D coins in the world and only Kazakhstan has the capacity to mint such coins.
On the issue of collection coins BALQASH ALABUǴASY
In the prototype, the perch head was 17mm higher than the plane of the coin. For artistic effect, the fish axis was given 10-degree vertical inclination during the production run.
The waves on the coin involved the development of a unique stamping washer and embossing tool.
The coins were unveiled on 3 February 2023 at the World Money Fair / World Monetary Conference in Berlin.
This set of collection coins is from the series ‘Flora and Fauna of Kazakhstan.’
The BALQASH ALABUǴASY (Balkhash Perch), as the name suggests, is found in the Lake Balkhash in Kazakhstan. This is the only natural lake in the world with two parts, one salty and the other fresh.
Balkhash perch is one of the endemic fish living in the lake. It separated from its closest relative, the common river perch, about 5-7 million years ago. It is included in the Red Book of Kazakhstan.
