Trading Cards, graded and raw.
Trading cards are the most data-rich category in collectibles. Grading services publish population reports, sold-listing data is dense, and condition moves price by an order of magnitude. The basics here will save you money on every submission.
What collectors look for
- Vintage and modern baseball, basketball, football, hockey cards
- Pokémon and other TCG
- Rookie cards and key first-appearances
- Sealed packs, boxes, and cases
- Inserts, parallels, refractors, and short prints
- Graded slabs (PSA, BGS, SGC, CGC)
What affects value
- Grade — the single largest driver in modern and many vintage cards
- Player significance and rookie status
- Set rarity, edition, and parallel type
- Population count at the assigned grade
- Authentication slip integrity
- Era and print quality
Authentication considerations
- PSA, BGS, SGC, and CGC are the recognized graders in cards
- Population reports are publicly searchable for each major service
- Raw card prices anchor to expected-grade outcomes
- Re-grades and crossovers carry their own risk
Selling tips
- Grade before selling if the card likely earns a 9 or 10
- Use sold-listing comps at the exact grade you have
- Bulk raw cards do best in lots — singles can underperform
- Ship in rigid sandwiches with insurance above $500
