This is a classic German States stamp from Baden, issued in 1853, denominated 6 Kreuzer in blue. The design features the Baden coat of arms supported by two griffins, with inscriptions “Freimarke” and “Postverein”. Printed imperforate on handmade paper, this issue was part of Baden’s first definitive series. The example shown is postmarked, adding postal history value. Despite edge wear and a heavy circular cancellation, this remains a significant 19th-century issue sought after by collectors of German States and European classics.
