 Kut Chum also achieved fame for issuing its own local scrip called "Bia Kut Chum".Bia, Thai for 'cowry shell', was once a unit of currency equal to of a Thai baht, and "bia" is still current in metaphorical expressions, so the usage ran afoul of currency laws.To side-step implications that they intended a substitute local currency, they changed to "Boon Kut Chum", which are barter coupons with a fixed value in baht, that may be exchanged for goods and services in the community.
