This coin was issued under the USSR, it is the largest denomination that was actually used every day as money. It is dated 1989 and it is dated both on the reverse and on the edge of the coin. You have the hammer and sickle on one side and the denomination on the other side. The current catalogue price is $30.00 in mint state 60 and there is no price for this coin in mint state 63, which they are. It is a scarce coin, in much better condition than they usually come. We bought them right, so we are going to sell them right. Uncirculated it catalogues at £22.70. A tough coin to get, especially so choice.
