To minimize kopiyka coin clutter

To minimize kopiyka coin clutter, customers paying cash can now round down their bill if it ends in 1-4 kopiykas. Shops are allowed to round up if the bill ends in 5-9 kopiykas. On Sunday, the central bank stopped issuing 1, 2, 5, and 25 kopiyka coins. It is not actively withdrawing these coins from circulation. The central bank continues to mint 10 and 50 kopiyka coins.
