Russia 5 Roubles 1898 АГ - Mint error - Nicholas II (1894-1917)
4.29g. Au 0.900. XF/AU. Mint error - Missing design element (Number 8 open in date). Bitkin 20; Sidorov 4981. Missing mintmarks, dates, and other design elements occur as the result of errors in the die or at the time of striking. A design element that is missing from the die when it is made is a fundamental error. Missing design elements that occur because dies are tilted and do not strike the planchet face-on are known as misaligned dies. A design element may be missing because foreign matter, such as grease, plugs the cavity into which the planchet's metal would normally flow under the striking pressure. This error is also known as a filled die or a strike through. Although this does involve a die, it is typically thought of as a striking error, but is included here for completeness.
