Reholder
A grading service operation that re-encapsulates an already-graded card or coin into a fresh slab without re-grading. Reholdering is used to refresh damaged or scratched slabs while preserving the original grade and serial number. Reholdering is significantly cheaper than a fresh grading service. The card retains its grade and provenance, but receives a new physical […]
Whatnot
A live-streaming auction platform where sellers break sealed product (booster boxes, packs, sealed cases) live on camera while viewers bid on individual hits in real time. Whatnot has become a major sales channel for sports cards, Pokémon, and other modern collectibles since 2020. Live breaking creates entertainment value but introduces risk: card-by-card pricing can vary […]
Rip & Ship
A common practice in trading card breaking where buyers purchase a slot in a sealed box; the seller opens (“rips”) the product on camera and ships any cards corresponding to the buyer’s slot. Variants include team breaks, division breaks, and random breaks. Rip & ship turns a single sealed box into many smaller transactions and […]
Whitening
A condition issue where a card’s edge or corner shows a white line or area, caused by impact, abrasion, or stacking pressure exposing the card’s underlying paper layer. Whitening is one of the most common reasons cards fail to achieve top grades. Even slight whitening invisible to the naked eye can show up under a […]
Dust Jacket
The removable paper cover wrapped around a hardcover book to protect it. The presence and condition of the original dust jacket can multiply a first edition’s value 5-20 times over the same book without one. Dust jackets should be preserved in archival mylar covers (Brodart or Demco), kept away from light, and never written on […]
Foxing
Brown spots or stains on paper, books, or prints caused by a combination of fungal growth and metal oxidation in the paper’s pulp. Foxing is most common in books and prints from the 18th and 19th centuries and is generally considered a defect that reduces value. Light foxing on text pages may be acceptable; foxing […]
Sleeper
A collectible that is undervalued relative to its long-term potential — typically because it has not yet been recognized by the broader market. Sleepers are the holy grail of bargain-hunting collectors. Examples have included pre-1980 video games before WATA grading, early Pokémon cards before the 2020 surge, and pre-2010 modular Lego sets. Identifying sleepers requires […]
Proof Coin
A coin produced specifically for collectors using polished blanks, polished dies, and multiple strikes to achieve a mirror-like finish. Proof coins are not intended for circulation and are typically graded on the same numerical scale as business strikes (with a “PR” prefix instead of “MS”). Modern proof sets are popular entry-level numismatic items; vintage proofs […]
Die Variety
A coin produced from a die with notable differences from the standard production dies — including doubled dies, repunched mintmarks, overdates, and clashed dies. Significant varieties are catalogued in references like the Cherrypickers’ Guide and command premiums over standard issues. The most famous die variety is the 1955 Doubled Die Lincoln Cent, which can sell […]
First Edition (Books)
A book printed during the publisher’s first print run of a title. True first editions are identified through publisher-specific points (number lines, statements on the copyright page, dust jacket prices, binding details) and vary by publisher and era. The most valuable first editions are typically first edition, first printing, with original dust jacket in fine […]
