The price of melanin has increased!!! Since we first reported the value of melanin it has gone up. Melanin is now worth $373.50 a gram (UPDATE: Melanin is currently worth $428 a gram.) That means the aromatic biopolymer and organic semiconductor that makes people black is worth $300 a gram more than gold. That is 6 times the value of gold. Melanin is important because it is valuable.
