孙中山认为,钱起源于货物交易,从本质上说,钱是人工劳动的价值体现。钱虽然对人们的日常生活影响深远,但金钱不是万能的,由劳动而来的货物能力才是巨大的。就钱币的质地、形态来说,钱币经历了从龟、贝、珠、玉到金、银、铜、锡再到契券、纸币的演变。钱币的出现和使用,既方便了人们的生活又促进了经济的发展。 Sun Zhongshan believes that the money originated in the transaction of goods, in essence, money is the value of labor embodied. Although money has a far-reaching impact on people’s daily life, money is not a panacea. The ability of goods brought by labor is enormous. As for the texture and shape of coins, the coins have undergone the evolution from turtles, shells, beads, jade, gold, silver, copper and tin to coupons and notes. The emergence and use of coins not only facilitate people’s lives but also promote economic development.
