A closer look

You are inherently valuable, but only by a hilariously pathetic microscopic margin. The human body naturally requires a massive slurry of trace metals to function, and among the iron, zinc, and copper, there is actual 24-karat gold floating through your veins. Mostly concentrated directly in your blood and joints, a typical adult possesses about 0.2 milligrams of pure gold. Unfortunately, before you try anything drastic, you would need to violently harvest the blood of around 40,000 people just to forge a single commemorative coin.
