Hello, Klyava
Thank you for your offer, but I don't really collect banknotes - except Kingdom of Yugoslavia, like stated on my profile. However, sometimes I can take few banknotes along the swap for coins, if someone offers them and if I find them interesting for me.
But something else was interesting for me:
"I am sorry that you do not have presence in Russia and the USSR banknotes.
I would then be exchanged."
Isn't it easier for you to find these banknotes in your country?
Personally, if I am looking for any coin or banknote from my country, it is easier to find it in - my country.
Best Regards
BK
