💬 Collector Notes
Independent editorial assessment
Old school spot with a tight vintage focus—think Mantle instead of modern wax. Not much for fresh sealed or TCG, but lots of raw classics and a few graded gems if you’re digging for PC stuff. Owner knows his history and isn’t about hype—expect more storytelling than slab flipping.
