I do not recommend it! The store makes prices out of thin air! Prices are one and a half, two or three times higher than the prices of the NBU (for coins of Ukraine) or coins of the world, which can be safely bought at a New auction, a club on Levoberezhnaya or a club on Nivki on Sundays.
Examples:
5 UAH. "Kurultai" I bought today in the NBU for 43 UAH. New Auction offers for 140 with delivery. It will be a little more expensive on the fields. In this "store" - 300 UAH.
Soviet gold 100r. "Olympic torch". The new auction is 19500 and there is no queue, there are 24000 here. Feel the difference.
