Yeah, it has relatively same value.

Main theory says that word "ruble" is related to "rubit'" (рубить, to chop). Like it was chopped part of grivna (old Russian money, that name remained in Ukraine). Ruble also have folk name "wooden".

I've never been in countries where these coins are made, except Bulgaria (and Russia of course). That's from old times of family.

Most coins are not rare souvenir rubles from USSR times though, only these on photo are relatively rare.
