Thailand. 1 Baht 1917 (No reserve price)

The 1 Baht coin from Thailand, minted in 1917, represents a period of modernization in Siam's monetary system under King Vajiravudh (Rama VI). The Baht remains Thailand's primary unit of currency, and early 20th-century coins reflect shifts from traditional to more contemporary coinage standards. Coins from this era often featured distinctive royal imagery and inscriptions in Thai script. Collectors view such coins as important milestones marking Thailand’s transition from medieval forms of money like Photduang to standardized modern currency, as well as the country’s efforts to integrate with global economic norms during the early 1900s.
