Money is a special commodity with universal equivalent, which is accompanied by exchange and is the product of exchange. In political economy, money has the functions of value scale, circulation means, storage means and payment means. The standard style is Yuanshou Wu Shu, Guanqian, Tang Yuanbao, and the weight is suitable for towels. About 4 grams. Gold includes irregular small square seal gold, small round seal gold, horseshoe gold, long strip gold, round cake gold and so on. The shapes of silver dollar are ingot, roller, wire board, ingot and strip. Because seashells are only found by the sea, they are rare, but relatively easy to obtain. People by the sea can be transported to the Central Plains, so they can continuously produce and meet the needs of ancient primitive commodity economy.
Looks like a lot of idiots are ready to be fooled again. I also believe that these fake auction companies that defrauded catalog fees, storage fees, appraisal fees and exhibition venue fees didn't wake up until they were cheated by tens of thousands: they met a liar! Not in the form of coins. In addition to the official silver minted by the government, silver houses, banks and even private individuals can also cast their own silver ingots. This leads to the fact that the shape, weight and fineness of silver ingots in actual circulation have no certain rules. Then put it on the raft and say, if it is broken silver, weigh it before using it. In addition, the fineness of silver should also be counted. If it is called tax, it should also be counted as fire consumption. So ordinary people are the source of copper coins and broken silver.
