eBay puts a ship-from location on every listing — it sets the item location buyers see and the shipping estimate. Enter the ZIP code your packages are mailed from.

What each field means, and how eBay files it.

Rookie (RC) — a player's official first-year card. eBay files it under Features.

Autograph — the card is signed. Format: Hard Signed (signed right on the card), Label or Sticker (a signed sticker applied at the factory), or Cut (a clipped signature set into the card).

Memorabilia (Relic) — has a real piece of material in it (jersey, bat, ball). A Patch is the premium kind: a multi-color swatch with part of a logo, number, or letter. eBay files both as "Memorabilia."

Serial Numbered — hand-numbered to a limited run, like 42/99. The total (the "/99") is the Print Run.

One of One (1/1) — only a single copy of the card exists.

Parallel / Variety — a colored or special version of a base card (Gold, Prizm, etc.). A Refractor is a shiny parallel, not a separate feature.

Insert — a special themed card inserted into packs, separate from the base set.

Short Print (SP / SSP) — printed in smaller numbers than the rest of the set (SSP = super short print), so it's harder to pull.

Graded — professionally graded and sealed in a slab (PSA, BGS, SGC, CGC). The Certification # on the slab proves the grade.

Card Thickness — measured in points (Pt). Thicker cards (35–360 Pt) are usually relic or patch cards.
