| Reverse description | The reverse depicts a detailed section of the Mendeleev Periodic Table of Elements, rendered across the entire field with multiple element tiles shown in grid formation, each bearing atomic number, chemical symbol, atomic weight, and Cyrillic element name. The zinc element tile (atomic number 30, symbol 'Zn', atomic weight 65.39, Cyrillic name 'цинк') is highlighted in the inlaid zinc insert at upper left of centre, distinguished from the surrounding silver field. A curved line sweeps across the table, evoking the natural grouping of elements. The legend 'QAZAQSTANÝN JER QOINAÝY' (meaning 'The Subsoil of Kazakhstan') arcs along the lower periphery in Latin script. |

| Additional information |
Kazakhstan's National Bank has issued a number of bimetallic collector pieces incorporating industrial metals as inserts, a format that gained traction among Central Asian mints in the 2010s as a way to add tactile and visual contrast to commemorative silver. Zinc, rarely used in modern precious-metal coinage, oxidizes readily and can develop surface character over time that distinguishes aged examples from freshly struck ones.
