On most Soviet era One Ruble coins, the USSR (CCCP) National (coat of) Arms is on the obverse, and other than Vladimir Lenin, various national symbols, heroes and icons would be on the reverse. On the post-Soviet era One Ruble coins, the Double-Headed Eagle appears on the obverse, and the value appears on the reverse.

"Obverse" refers to the front of the coin (usually the side with the portrait), as versus the "reverse", or back, of the coin.
The reverse of any coin is its back. The portrait is on the obverse, or front.
The term "reverse" refers to the back side of a coin, as opposed to the "obverse", or front side. On US coins, the obverse side is the one with the portrait and (except for the presidential dollars) the date. On foreign coins, it is not always easy to determine which side is the obverse and which is the reverse, although a good rule of thumb is that the side with the portrait, crest, or name of the country is probably the obverse.
