Minters used the same forms for the platinum and traditional silver coins, but platinum is twice as heavy as silver, and it was approximately 6 times more expensive than silver at the time. The platinum three ruble coin had the same size as the silver 25 kopek (0.25 ruble) coin; it weighed twice as much and was thus valued 12 times higher. For this reason, the coin is specifically marked as "3 rubles per silver" (). The same reasoning applied to the 6- and 12-ruble coins. The coins were minted from native Ural platinum. It was not free from such noble metals as iridium and palladium, and thus the accompanying phrase "pure Ural platinum" () only meant that no metal was intentionally added in production.
