REAL-SALE EVIDENCE + ALL-IN MATH

Research the sale.
Stress-test the deal.

Search trusted sold-price archives, paste the closest real results, and turn them into a range, evidence score, and buyer or seller decision.

SAMPLE numbers demonstrate the interaction. They are not current comps or a valuation.

Use this as a decision aid, not an appraisal. Confirm the exact item, sale date, condition, authenticity, buyer's premium, taxes, and shipping at the original source. A median can be wrong when the matches are wrong.

A COMP IS ONLY AS GOOD AS THE MATCH

Match the item.
Then trust the math.

Price alone is not a comparable sale. Confirm the date, mintmark, variety, grade, holder, condition, authenticity, sale date, and buyer's premium. When those details do not match, the number may create false confidence.
