Start by checking the denominator
A card rising from 100 dollars to 300 dollars gains 200 percent. A card moving from one unusual 10 dollar sale to one 1,000 dollar sale gains 9,900 percent. The second headline is larger, but the comparison may be much weaker.
Separate liquid cards from rare grades
PriceCharting reported more than three thousand recorded PSA 10 sales for Pikachu with Grey Felt Hat in its August modern volume review. That depth makes its reported twelve month rise easier to examine. A population one trophy card requires a completely different standard.
Look for confirmation after the record
One sale establishes a high. A second and third transaction near the same level begin to establish a market. Until then, write record sale, not new value. Check whether lower grades and raw copies moved in the same direction or remained unchanged.
Do not turn backward looking data into a promise
A twelve month chart describes what buyers already paid. It cannot show that the next buyer will pay more. New supply, a reprint, broader economic conditions or attention moving to another character can reverse the chart.
The best use of a gains list is research prioritization. It tells you which sales histories deserve a closer reading.
