8 Incredible Things Sold for $1

7. Insulin formula

Sir Fredrick G. Banting, a scientist, figured out how to produce and purify insulin from animals in 1921. Millions of lives have been saved thanks to this incredible medical advancement. The first diabetic patient to get insulin was treated on January 11, 1922, and the outcome was remarkable. But Banting felt it was unethical for a doctor to earn from something that could benefit so many people, therefore he declined to profit from his discovery. Regretfully, Fredrick lost control of his wonderful innovation after selling the formula. It’s unfortunate that not everyone can obtain the medicine as easily as he had intended.
