5 Chervontsev Suminia

The chervonets denomination has a complicated Soviet history — originally a hard-currency gold coin introduced in 1922 to stabilize the post-civil-war economy, it was deliberately positioned against the inflated sovznaki ruble. Reviving the name in 2025 for a nickel silver issue from the Moscow Mint is an unusual editorial choice, borrowing prestige from a denomination that hasn't seen regular production in decades.

Without confirmed mintage figures or an authoritative source on the "Suminia" series context, further attribution would be speculative.
