There are 100 Kopeks in a Russian Ruble. See link to Universal Currency Converter. Using the Universal Currency Converter, you can convert any denomination from any current currency, into the equivalent value of any other current currency. It is updated regularly, so whatever you see will be relatively current. Global currency values can change from time to time, but currently a Russian Ruble is about 3 US cents. ($0.03)
Not much. The Ruble is not widely traded, if at all, on the money market. A beggar will turn his nose up at a Ruble. You can make a local telephone call for One Ruble. The current exchange rate for One Ruble is about 2 Pence GBP or about 3 cents USD.
Value depends on condition and denomination. The three denominations issued in 1938 are 1, 3 and 5 Ruble which are worth $15/$25/$25 in mint uncirculated condition, dropping to $4/$5/$7 in very good used condition.
The lettering on the coin is almost certainly in the Cyrillic alphabet used in Russia and some other Slavic countries. "ру́бль" means "ruble" which is Russia's main unit of currency so your coin is most likely from that country. The ruble trades at roughly 30 to the US dollar so a 1 ruble coin would be worth around 3 cents.
About 3 pennies. ;D
If I have read your mis-spelled question properly, you have a 1995 copper/nickel Bank of Russia (БАНК РОССИИ) 20 Ruble (ДВАДЦАТЬ РУБЛЕЙ) coin 24.1 mm in diameter with a double headed eagle on the obverse and soldiers and tanks on the reverse. A Russian 1995 Twenty Ruble (РУБЛь) coin, uncirculated and in absolute mint condition could fetch up to $3 USD. A reputable coin dealer will be able to give a more accurate valuation.
Russia does not use cents or dollars, it uses rubles and kopecks. It's more likely that your coins are in rubles because the kopeck is 1/100 of a ruble and has very little value so low-denomination coins are not often used. In any case it's not likely that your coin is worth a huge amount because as of early 2011 the ruble is trading at roughly 3¢ US. If you need a specific please check your coin again for its denomination and post a new question (don't add to this one). The denomination will be in the Cyrillic alphabet: рубль = ruble копе́йк = kopeck
The value of a bulls head 3 dollar bill from 1864 will depend on the condition. A bill is fair to good condition is worth an estimated $50.00 US dollars.
The US never issued a $3 bill. The only $3 denomination was a coin made in the mid-19th century.
Very little. Your coin is from Russia, so its value would be in either kopecks or rubles rather than US cents. Either way, as of mid-2013 the ruble trades at about 3¢, so if it's 10 kopecks it's worth 0.3 US cents; if it's 10 rubles it's worth 30¢. The lettering on the coin is in the Russian alphabet and is actually "Банк Россуии" which translates as Bank of Russia.
