The money that was once minted in the Urals was among the most expensive in Russia. The fact is that their price is determined not by face value, but by uniqueness, chelTV reports.
The issue of unusual coins started in the 18th century. In shape, they resembled a rectangle or square and were called copper tiles. They were made of pure red copper. Square coins included pennies and rubles.
In total, in 1726 square boards were minted for a total amount of more than 43 thousand rubles. The money turned out to be very heavy, as their face value was equal to the cost of a piece of copper. For example, a ruble coin weighed about one and a half kilograms.
It was inconvenient to carry such a penny, so they never became popular among the people. As a result, monetary reform was curtailed, and all copper boards were withdrawn. Now, these coins are very rare and expensive; the cost of a square coin can reach up to two million rubles.
