Issued under the Bank of Lithuania's long-running commemorative program, which has built a reputation for technically ambitious themes unusual among European central banks. Lithuania has been particularly aggressive in using numismatic issues to engage with technology and science subjects — this gold piece continues that pattern. The .917 fineness is standard crown gold, the same alloy used by the British sovereign series for centuries.
