Terms of Use & Disclaimer

Grade Edge LLC operates Margin Scope, a sports card analytics tool that provides estimated price data, margin calculations, and grading opportunity insights based on publicly available eBay listing data.

We are a data and analytics tool. We are not a financial advisor, investment advisor, or broker. Nothing on this website constitutes financial advice, investment advice, or a recommendation to buy or sell any specific card or asset.

The prices shown on Grade Edge are estimates derived from recent eBay listings. They are not guaranteed sale prices, appraisals, or market valuations.

• Raw card prices are estimated from active and recent eBay listings and may include both sold and unsold listings.
• PSA 10 prices are estimated from recent graded card sales and may not reflect current market conditions.
• Margins shown are the difference between estimated prices and do not account for all costs (shipping, fees, grading time, etc.).
• All numbers update based on available data and may change significantly between sessions.

Always verify current prices on eBay, PWCC, or other marketplaces before making any purchasing decision.

PSA population reports and gem rate percentages are historical statistics based on cards already submitted. Your specific card may grade differently. Cards that show high gem rates in our tool have historically graded well across the population — not necessarily the individual card you are considering.

You should personally inspect every card before submitting for grading. Grade Edge accepts no responsibility for cards that do not achieve a PSA 10 or any specific grade.

Margins shown in Grade Edge are pre-grading estimates. Your actual profit will depend on:

• The PSA grading tier you select and its associated fee
• Shipping costs to and from PSA
• eBay or platform selling fees (typically 12–15%)
• The actual grade your card receives
• Market conditions at the time of sale
• Turnaround time and opportunity cost

Use the PSA grading cost toggle in Margin Scope to model your net profit after grading fees. Always run your own numbers before purchasing.

Grade Edge is a starting point for research, not a final answer. Before buying any card for grading purposes, we strongly recommend:

• Physically inspecting the card under bright light for surface issues, scratches, and print defects
• Checking current eBay sold listings yourself — not just our estimates
• Reviewing the current PSA population report for that specific card and parallel
• Considering current grading turnaround times and their effect on your capital
• Understanding that card markets can shift quickly and past margins may not reflect future results
