The Future of the US Dollar

So I am cleaning, for it is good to clean, and in my effort to lessen the amount of junk I have, I stumbled upon some old Soviet (I think) currency, that no doubt is worthless, because, well, as the leftists in this nation are about to find out, a piece of paper is just a piece of paper unless you actually have some level of production behind it.

All that being said, does anybody know what i have here? I collected coins as a youth, but I know very little about currency.
