Medal - 10 Miedziaków chroniących przyrodę - Poskocz Krasny Mosiądz

MET operated as a private Polish token and medal issuer producing small educational series during the early 2010s, and this piece belongs to a ten-medal set dedicated to protected Polish fauna. The Cordulegaster heros — the poskocz krasny, a large dragonfly species native to clean, fast-flowing streams in southeastern Poland — was added to the Polish Red List of threatened species, making it a logical subject for a conservation-themed collectible series.

Private brass medals of this type circulated almost exclusively through numismatic shops and nature education programs rather than general commerce.
