Pace trend
Holding steady21 new slabs in the last 4 wks, vs 10 in the 4 wks before — too small a sample for an 11-slab difference to mean anything. Not a change in pace.

744 slabs
Only 31 new slabs in the full 8-wk window this reads over — this card is graded too slowly for a reliable fresh-quality read. That's normal for vintage and low-volume cards, not a sign to check back later.
