Just as an advice to potentially start swapping. You don't have any coins to offer basically. You just put 2 common coins that most people already have. Even if they don't have them and even if they want to swap them, it won't be worth paying for the shipping just for those 2. So you need to add a lot more to offer to try to get something.
My advice, put 2 euro commemorative coins, especially from Latvia or other Baltic countries especially of the recent years, the newer, the better. It is easier for you to get them from circulation. Quite a few people will be interested in them, and they will be happy to swap them for some soviet coins you want.
