The top two kopeika denominated notes are for a Beriozka or hard currency store. Regular USSR citizens could not shop in these stores with regular ruble or kopeks. These stores were where you could buy western electronics, liquor, cigarettes etc. They had them in most of the larger cities, and they were mostly for the apparatchiki, the privileged class. I shopped in one in Khabarovsk for western soda once, their prices were very high. The values on these are mid-range, they are rather scarce.
The last two are bond coupons for WWI Russian bonds, these were delivered to and used in Siberia as money when cut up though. These have nominal value.
