Can anyone help identify possible cash coin/token? [resuelto]

Small coin appears to be brass. Circular hole in square design seems unusual. I could not find in China or Vietnam. Any comments on origin of coin or token welcome.

Interesting history! So these were mafe for what purpose?

Anyway, they don't cost anything, using existing equipment and material to strike tokens for celebrating the victory and keeping for souvenirs.
