《宋史·列传·卷九十一》
当时铸钱法败坏，议论的人打算变大铁钱当作一小铜钱，陆诜说： 民间向来重小铜钱而贱大铁钱，以后以一当三还是轻了，现在减少命令平均其值，大钱必定会废弃。
时铸钱法坏，议者欲变大钱当一，诜言： 民间素重小铜钱而贱大铁钱，他日以一当三犹轻之，今减令均直，大钱必废。
At that time, the coinage system was in chaos, and people who had discussed the issue intended to change large iron coins to be worth a small copper coin. Lu Shen said: The public has always valued small copper coins and depreciated large iron coins, and changing the ratio of their value to one to three is still not enough; let's instruct the government to equalise their value, and then the large coins will inevitably be abandoned.
