| Additional information |
Kazakhstan's National Bank has produced a number of bimetallic collector issues pairing silver with refractory metals, and tantalum — a dense, corrosion-resistant element more commonly found in capacitors and surgical implants than in coinage — appears in only a handful of issues worldwide. The combination is technically demanding; tantalum's extreme hardness makes die wear a genuine production concern, and achieving a clean bond between the tantalum planchet and the silver ring requires tolerances that most mints cannot maintain at scale.
The specific turtle depicted belongs to Kazakhstan's protected fauna series, part of a broader program documenting species native to Central Asian ecosystems. KM#367 was struck in limited numbers for the collector market and saw no circulation.
