"Is this card worth sending to grading?" — Subtract the raw price and grading cost from each grade's sold price and you have the answer. Duck Stock computes per-grade estimated profit from real eBay and Bunjang sales data.
On a card page, the "Grading Value" table shows graded price − raw price − grading cost = estimated profit per grade.
Grade probabilities and grading costs are estimates and may differ from actual grading results and fees. This calculator is reference information, not investment advice.
