Today, at the local weekly coin market, I have acquired these interesting pieces but I have no idea of what they are. With our tool "Advanded search: Metal=porcelain" but I find nothing...
With such simple inscriptions, I would suggest board game pieces. Such board games have been around for hundreds if not thousands of years. Or perhaps counters/jetons.
Siamese porcelain tokens used in the gambling houses of Thailand, starting around 1868 or slightly later; most were made in China. I was only able to identify P2.
P2 side 1: Ch’ien (the value of the token).
side 2: Shun - Ts’ai (quick wealth).
