Vintage Chinese Wood Abacus Suanpan 13-Rod 2:5 Bead Configuration

The Vintage Chinese Wood Abacus Suanpan is a traditional tool of calculation originating from China. With a 13-rod and 2:5 bead configuration, this ancient artifact represents the rich cultural heritage of Chinese mathematics. This historic piece is a unique collectors' item that embodies the intricate craftsmanship and cultural significance of Chinese society, making it a valuable addition to any collection focusing on Chinese collectibles. Based on the physical details visible across both images, your abacus is highly consistent with a mid-to-late 20th-century vintage utility abacus (roughly 1950s–1980s) rather than a rare centuries-old antique. During the mid-to-late 1900s, millions of these robust, high-quality suanpans were mass-manufactured for merchants, accountant guilds, and schools across Asia.
