5000 Francs Tea Horse Road

The Tea Horse Road — known in Chinese as the Chamadao — was the network of mountain trading paths connecting Yunnan and Sichuan provinces to Tibet, active for over a millennium. Compressed tea bricks were the primary commodity heading west; horses, critical to Chinese military capacity, moved east in return. The trade sustained entire regional economies and shaped Tibetan material culture more durably than any political arrangement managed to.

Cameroon's involvement is purely fiduciary — the republic has issued dozens of large-format silver pieces under licensing arrangements, with the coins designed and marketed entirely by European distributors targeting collector markets.
