This uncirculated 20 Yugoslav dinar banknote is a back-proof note printed by the National Bank of Yugoslavia. It is a gray banknote that is dated 1951 and measures 118 mm x 58.5 mm. Due to a printing error, it does not have an obverse design. Its reverse side shows the Yugoslavian coat of arms. Because it is a back-proof banknote, it does not have a security thread or a watermark.
