The object illustrated and discussed is a Chinese silver ingot (sycee), but the stamps on it are fake. I listed over 40 such fakes (many published by Mitchiner) in my catalogue (pp. 305–310) where a genuine ingot has been given added value by the addition of date and place stamps.

This ingot shape came from Sichuan Province and normally weighs c. 360g (10 liang) or c. 180g (5 liang). This is most likely an unstamped genuine piece to which fake stamps have been added, but I cannot rule out the possibility that the ingot is as fake as the stamps.
