This carved jade charm coin represents the Taoist protective talisman known as the “Mountain Demon Thunder Bureau” 山鬼雷局 (Shān Guǐ Léi Jú). These pieces were not used as currency but were created as ritual or protective amulets associated with Taoist practices. The front displays inscriptions referencing the Mountain Demon and the Thunder Bureau, symbols connected with Taoist exorcistic traditions and divine protection. Such charms were believed to ward off evil spirits, prevent misfortune, and bring safety and prosperity to the household. The reverse side depicts the Eight Trigrams 八卦 (Bāguà), the fundamental cosmological symbols from the I Ching 周易 (Zhōu Yì), representing balance and harmony in the universe. Carved from jadeite with a traditional square central opening reminiscent of ancient Chinese coins, this piece combines symbolic meaning with decorative craftsmanship. It is valued as a Feng Shui object, collector’s item, or spiritual amulet associated with protection, luck, and prosperity.
