10 Roubles Tyumenskaya Oblast

Part of the long-running Russian Geographical Series, this issue marks Tyumenskaya Oblast — a region whose economic significance stems almost entirely from the West Siberian oil and gas fields discovered there in the 1960s, which transformed it into one of the wealthiest federal subjects in Russia. The oblast contains Khanty-Mansiysk and Yamalo-Nenets autonomous districts, which are administratively subordinate to it but produce the bulk of Russia's hydrocarbon output.

The Bank of Russia has issued well over 100 bimetallic 10-rouble pieces in this regional series since 2005, and collector fatigue has kept secondary market premiums modest for most common-date examples.
