Phật Pháp Tăng Bảo. This coin is overtly Buddhist because it uses the three words that comprise the Buddhist phrase “Three Treasures” (三宝). Those three words are the Buddha (Phật/佛), the Dharma (or law) Pháp/法) and the Sangha (or community) Tăng/僧). Thierry suggests this coin was probably produced by a large Buddhist monastery.
