The hobby runs on shorthand, and almost nobody explains it. RC, XRC, SSP, PWE, pop report, qualifier, FOTL, IOSS — all of it gets used as though everyone already knows. This page defines what people are actually saying, and links onward wherever a term deserves a full explanation. Search it, filter it, or link straight to any single definition.

A
Acid-free
Supplies & storageStorage material chemically stable enough not to damage cards over time. Look for this and for non-PVC on any sleeve packaging.
Active listing
Marketplace & slangA card currently offered for sale. An asking price, not evidence of value — anyone can list anything at any price.

Read more →Authentic
Grading & slabsA designation meaning the card is genuine but was not assigned a numeric grade, often because it has been trimmed, altered or is otherwise ineligible.

Binder filler
