In 1931, the value of the Russian rouble was quite unstable due to the economic turmoil following the Russian Revolution and the subsequent civil war. At that time, the official exchange rate was approximately 1 rouble to 0.25 US dollars, but this value fluctuated significantly due to hyperinflation and other economic factors. It's important to note that the rouble had different values in various contexts, including official rates and black market rates.

I presume that you are referring to a circulated US 1931 cent with no mintmark under the date, rather than a British penny. The answer then is almost certainly under a dollar.

In circulated condition, the 1927, 1930, and 1931 may be worth a dollar or two, but the rest have little or no added value.
