Plain-English definitions for every term used on GradeScout.

Pricing & Market Data

Raw price
The TCGPlayer market price for an ungraded card — what you would pay to buy it today. This is the starting cost in every ROI calculation.
Smart price
PokemonPriceTracker's best estimate of a graded card's current market value. It filters out outlier eBay sales (suspiciously high or low) and weights recent sales more heavily than older ones. More reliable than a simple average or median.
Confidence
How much to trust the smart price, based on how many recent sales are available.
  • ● high — many recent sales, reliable estimate
  • ● medium — some data, reasonable estimate
  • ● low — few or old sales, treat with caution
7-day delta
The percentage change in PSA 10 smart price over the last 7 days. A green ↑ means the card is getting more valuable; a red ↓ means it's declining. Only shown when the change is at least 1%.
Trend
The market direction for a graded card based on recent eBay sales patterns.
  • ↑ Trending — price is rising
  • ↓ Trending — price is falling
  • → Stable — price is flat
Daily volume
The average number of eBay sales per day over the last 7 days. A card with 0.2 sales/day is illiquid — it might take weeks to sell. A card with 5/day will move quickly.

ROI & Filtering

ROI
Return on investment — what you make after grading costs, as a percentage of what you put in.
ROI = (graded price − raw price − grading fee − shipping) ÷ (raw price + grading fee + shipping) × 100

A card that grades at $100 when you paid $40 raw + $25 grading + $20 shipping isn't 150% ROI — it's actually 18% after fees. GradeScout always includes fees in the calculation.

Diamonds ♦
Cards where ROI is greater than 50% AND the raw price is under $30. The ROI threshold filters for meaningful profit margin after fees. The $30 cap filters for accessibility — most collectors aren't speculatively grading $100 raw cards. The combination identifies cards where grading is both profitable and reachable.
Gradeable cards
Cards that have graded eBay price data for the selected service. Commons and uncommons typically have no graded market — they're excluded from stats like median raw price so the numbers stay meaningful.

Grading Services

PSA
Professional Sports Authenticator. The most widely traded graded card company. PSA 10 (Gem Mint) is the standard benchmark for grading ROI. Highest resale liquidity of any grading service.
BGS
Beckett Grading Services. Uses sub-grades (centering, corners, edges, surface) to produce a composite score. BGS 10 Pristine means all sub-grades are 10. BGS 10 Black Label means all sub-grades are a perfect 10 — rarer and worth significantly more.
BGS Black Label
A BGS 10 where every sub-grade (centering, corners, edges, surface) scores a perfect 10. Much rarer than standard BGS 10 Pristine and can be worth 5–10x more. GradeScout shows Black Label as a separate column when BGS is selected.
CGC
Certified Guaranty Company. Growing market share in Pokemon cards. CGC 10 Pristine is their top grade. Turnaround times and fees are competitive with PSA.
TAG
Technical Authentication & Grading. Smaller grading service with a niche following. Lower population counts mean some TAG 10s command premiums for rare cards.

Grading Tiers & Fees

Economy tier
The slowest, cheapest grading option. Best ROI on the fee math, but longest wait time (months). Good for cards you're holding long-term.
Regular tier
Standard turnaround. The middle ground between cost and speed. Most collectors use this for cards they want back within a few weeks.
Express tier
Fast turnaround at a premium fee. Higher cost means lower ROI — only worth it if the card is time-sensitive (e.g. a card trending hard right now) or you need it back quickly.
Tier optimizer
The three-column breakdown in each card's expand view showing ROI for all three tiers side by side. Helps you see at a glance whether express is worth the fee premium for that specific card.
Shipping (roundtrip)
GradeScout includes estimated roundtrip shipping cost in every ROI calculation. Shipping to and from the grading company is a real cost that most ROI tools ignore.

Fees and thresholds are updated periodically. ROI figures are estimates based on recent eBay sales data — actual results depend on card condition, grading outcome, and market timing.
