Huligan, you should wait for the page to load completely or refresh it. The server is on a notriously slow server.
Roberto, that site DOES have all the infomation but you will need to read Russian. All catalogues that I know are in Russian so it will be very pointless if I did try to recommand any.
That particular coin that I have shown is rather difficult to find, which is a restruck coin of Engels 1985 but the die is accidently muled with a 1983.
The 1958 set is extremely difficult to find as well as extremely pricey. Unless you have hundreds to spend, if not thousands, I wouldn't bother. The 2,3 and 5 rubles are extremely expensive.
