The seals were not money, but were stamp seals, used for stamping packages. They were carved on steatite, a soft stone. It seems that families of merchants had adopted certain domestic animals as totems. That is why they engraved their likeness on the seals. From the ruins of a warehouse at Lothal 71 sealings were recovered, most of which bear impressions of cloth used for packing the cargo which was consumed by the fire. Circular plano-convex pieces of clay, according to B. B. Lal, may be regarded as tokens carried by merchants or their messengers. - [Previous: v1.c19.s6.5](https://indike.org/pramana/ins.science.randhawa-1980.v1.c19.s6.5) - [Next: v1.c19.s6.7](https://indike.org/pramana/ins.science.randhawa-1980.v1.c19.s6.7) - [Up: v1.c19.s6](https://indike.org/pramana/ins.science.randhawa-1980.v1.c19.s6) ## Cites (1) - [Lothal](https://indike.org/pramana/inp.site.lothal) --- Source: [https://indike.org/pramana/ins.science.randhawa-1980.v1.c19.s6.6](https://indike.org/pramana/ins.science.randhawa-1980.v1.c19.s6.6) · Pramāṇa
