It is worth noting the special interest of collectors in some kind of unusual issues of the NBU - plates, medals, tokens. NBU plates are souvenir money made of silver, weighing 4 ounces and in denominations of 1, 2, 5, 10, 20, 50, 100, 200, 500 UAH. The National Bank of Ukraine also minted commemorative medals and tokens. They were produced from both inexpensive and expensive metals. This is, in a way, a separate topic of collecting.
