Harry arched an eyebrow, looking at the man. "So... a lump of gold, just sitting around?" He smirked, just a bit. "I can tell you, no, I haven't. I could remind you that the men in the white coats have all our personal belongings. I could tell you it was stolen by the Summer Lady of the Seelie Court and she took it to the Nevernever. Her name is Lily, by the way. Sweet kid. Green hair. But really, if just comes down to how much you trust that a potentially crazy wizard didn't just steal something shiny because it's shiny."
Then Harry shrugged. "Haven't seen it." Then, he hesitated for just a moment, and said, "But I'm pretty good at finding things. Kinda my job."
