Why are coins round and not square or cubes, etc.?
In: 265
While vending machine theory sounds good ( and there were vending machins 2000 years ago). The real answer is following:
Round shape with little teath was best to reduce frauds. The most major was to grind some gold from side. If grinding was done uneven than shape was clearly not round. And it was quite hard to grind round coin evenly. Things become even more harder when theath was introduced around edge. The made distinguish between grinded and non grinded coins much easier.
