CARD VALUE CENTER

What is your card actually worth?

Start with completed sales, match the exact card, account for condition, and separate raw value from graded value. No instant-value gimmicks.

GRADED VALUE COMPARISONS

Think in percentages, not just dollars.

IQCardGuide will compare high-grade resale premiums against comparable raw cards using percentages so a $20 card and a $2,000 card can be evaluated on the same scale.

Primary comparison set: PSA 10 · BGS 10 · BGS 9.5 · CGC 10 · SGC 10 · TAG 10

Published averages should include sample size, sales window and last-updated date. Individual-card sold comps remain more important than any grader-wide average.

Our first card profile applies the methodology to a high-volume Pokémon card and leaves thin grade buckets clearly labeled.

COMMON MISTAKES

Don't let one number fool you.

Asking price ≠ market value

A seller can ask any price. Completed sales show what buyers actually paid.

One sale ≠ the whole market

Use several comparable sales when possible, and notice whether prices are rising, falling or scattered.

IQ RULE

Value is a range,
not a promise.

Condition, timing, venue, buyer demand and exact card details can all change the price. IQCardGuide is designed to help you make a better estimate—not manufacture certainty.
