On 15 October 2025 the Czech National Bank is putting into circulation a CZK 200 commemorative silver coin to mark the 900th anniversary of the death of chronicler Cosmas. The coin is minted from an alloy containing 925 parts silver and 75 parts copper and is issued in two versions, normal quality and proof quality, which differ in surface treatment and edge marking. Proof-quality coins have a highly polished field, a matt relief and a plain edge with the inscription “ČESKÁ NÁRODNÍ BANKA * Ag 0.925 * 13 g *”. Normal quality coins have milled edges. The coin is 31 mm in diameter, weighs 13 g and is 2.25 mm thick. As with any other coins, deviations in diameter of 0.1 mm and thickness of 0.15 mm are allowed. Upward deviations in weight of 0.26 g and silver content of 1% are permitted.
