About this site and the person who runs it
My name is Will. I teach 8th grade science. I have collected cards my whole life, and I still do. I buy and I sell.
Card prices are inconsistent across sites. Some show asking prices nobody paid, some blend graded and raw sales into one average, and most do not say where the number came from or when it is from. That is a slow way to work, and it is a bad way to work when you are guessing.
I buy and I sell, so a number that leans either way costs me about half the time. And I spend my days telling students that a claim needs evidence behind it. It felt strange to keep accepting prices that came with none.
So I built the thing I wanted. A price I can trace back to real sales, with dates attached, and a plain note when there are not enough sales to say anything useful yet. If a card has not traded, I would rather the site tell you that than invent a number.
I still teach. I still buy and sell, and I use this site before I list a card or make an offer. When a price here is wrong, it costs me too.
What DataNeverLies is
DataNeverLies is a card pricing site: it tracks what cards actually sell for and shows the price next to the sales behind it. Anything it has to estimate is labeled an estimate, and when there are not enough sales to say something honestly, it says so instead.
Where the prices come from, how a percentage change is calculated, and what gets withheld are all written out on the methodology page. If you would rather see what the site actually does, start with What is DataNeverLies?
