💬 Collector Notes
Independent editorial assessment
This spot’s got a nice mix—plenty of wax to rip and a decent wall of high-end if you’re looking for slabs. You’ll find some older junk wax and mid-tier autos, but don’t expect deep bins of bargain raw cards. It leans more sports than TCG, and while the prices aren’t steals, things are fairly comped.
