OP: Why couldn’t traditional Chinese Yinpiao银票/silver drafts be forged if they were merely slips of paper? (cr大明宝钞，渐越)

Traditional Chinese yinpiao/silver drafts were paper vouchers issued by private banks starting from the Song Dynasty(960–1279). People could exchange these slips for physical silver at bank branches across the country.

Silver drafts were made in multiple copies with matching serrated seal edges. One copy went to the customer and others stayed at the bank. All edges had to fit perfectly together to withdraw silver. The unique split edge marks were almost impossible to copy.

This mechanism is known as qifeng骑缝 (split-joint seal) in China. It first originated in the Western Zhou Dynasty (1046–771 BC). The Rites of Zhou records that contracts were written on bamboo or wooden slips in duplicate. Notches and marks were carved in the middle before splitting the slips, with each party keeping one half. The two halves would be matched by their notches for verification.

During the Spring and Autumn and Warring States periods (770–221 BC), this idea evolved into hufu虎符/tiger tally tokens. A military tally was split into two pieces with identical inscriptions carved along the split edge. Troops could only be deployed if the patterns and characters on both halves perfectly aligned, serving as a metal version of the split-joint anti-counterfeiting system.

The technology matured in the Tang Dynasty (618–907). Government documents and private contracts commonly used split-joint seals stamped across the dividing line. The Chinese character "hetong合同" (contract) was written across the middle before the paper was torn apart, so the complete characters would only appear when the two halves were put together. This split-coupon system was later adopted for Song Dynasty (960–1279) jiaozi paper money and yinpiao/silver drafts of the Ming and Qing dynasties (1368–1912).

Official Song dynasty paper money (Jiaozi交子) was abolished in 1107. Private silver drafts issued by Qing-era piaohao票行 (ancient exchange banks) vanished completely in 1951, hit hard by modern banks and currency reforms. Nowadays silver drafts no longer circulate as currency. Their collectible value depends on their rarity and physical condition.

Now as an adult working in security I get SO MANY folks- upper-middle aged mostly- coming to me to 'rat out' people they think are faking it.

I was once sent into a bathroom because a client demanded that the "fucker won't get out, so go drag them out"- I was NEVER going to do that, so I did a wellness check instead. You know who it was? A person recently released from the hospital after a car accident. They had a hole in their skull and major hearing loss. They couldn't answer the owner because they couldn't HEAR the owner.

Another time about a homeless man who got around town by kicking the ground from his wheelchair. "You know he doesn't actually need that thing, his legs work fine, it's just for pity points"- Oh, so he's not paralyzed, his wheelchair is performative? Funny story Dale, I actually know that guy, he was backed over by a truck and has chronic pain from his shattered pelvis. But sure, let's make him stand up and walk everywhere so nobody feels too bad for him and tries to help him or something.

"She doesn't need that scooter, I've seen her get out of it."

"Look how fat he is, because he just rides around and refuses to get up."

"She doesn't really need that cane- she comes here without it all the time"

The only things that work without rest are machines; literally everything that lives requires rest.
