Modern Era / Reign of King Rama IX (1946-2016). This specific design reflects the late 20th and early 21st-century Thai monetary system.
Age Estimate
The date on the coin appears to be B.E. 2551 or similar, which corresponds to 2008 A.D. This design was minted between 1988 and 2017.
Cultural Significance
Represents the long-standing Thai tradition of featuring the monarch on one side and a significant religious site on the other, reinforcing the connection between the Monarchy and Buddhism.
Condition Notes
Good to Very Good (Circulated). Visible surface wear, light scratches (bag marks), and minor verdigris/tarnish spots typical of copper-based alloys exposed to moisture. No major structural damage.
Value Estimate
Nominal value (approx. $0.14 USD) as it remains legal tender in Thailand. Collector value for circulated examples is minimal, typically found in 'world coin' bins for $0.25 - $0.50.
Care & Maintenance
As this is base metal currency, avoid acid-based cleaners which can damage the cladding. If collecting, store in a PVC-free flip to prevent 'green slime' verdigris from the copper content.
Similar Pieces
Older 5 Baht coins (e.g., 1972-1987) which were larger/decagonal; silver commemorative Thai coins which carry actual .900 or .925 purity hallmarks.
Interesting Facts
Despite its silver appearance, the 5 Baht has not contained precious metal since the 1960s. The temple depicted, Wat Benchamabophit, was built entirely of Carrara marble imported from Italy.
