Today in this 18-part limited series we’re talking with John, co-host of the Global Card Collectors podcast and @Istanbulcards on Instagram. John is a basketball and soccer collector. He’s thoughtful. He’s deliberate and disciplined. Yet anyone, even collectors who stay on their path, are not immune from a painful lesson: Not all 1-of-1s are created equal.
