A one-to-ten star rating on every card, explained in kid words
The star rating answers the question every kid asks first: is this a good card? It blends three things — how many collectors are looking for the card right now, how scarce the printing is, and which way the card is moving — into one number from one to ten, with a sentence that says why.
What goes into the number
Demand: how many live listings and recent searches the card has across the hobby. Scarcity: whether the printing is numbered, a short print or a base card. Momentum: whether the card has been rising or falling over the last weeks. The three are weighted, and the weights are the same for every card so ratings can be compared.
What the number is not
It is not a price and it is not an appraisal. A ten-star card can be worth a few dollars; a quiet five-star card can be a long-term keeper. KidCard shows the reasoning next to the number so a kid learns to read the market instead of trusting a score.
Ratings change, and that is the point
A rookie who breaks out moves up. A set that floods the market moves down. Your kid’s vault re-rates as the hobby moves, and the Card Pulse page shows who is trending each week.
Parent view
Parents see the same rating and the same sentence. Nothing about the rating is hidden from the grown-up, and nothing is sold on the strength of it.
Questions parents ask
›Is a 10-star card valuable?
It is wanted and scarce right now. Value depends on condition and the buyer; KidCard shows live listings so you can see what people actually pay.
›Can my kid influence the rating?
No. The rating comes from hobby-wide data, not from likes or trades inside KidCard.
›How often do ratings update?
Several times a day for trending players and at least weekly for everything else.
›Does the rating use card prices from other sites?
It uses live marketplace listings and our own history. Where a third-party price guide contributes, only our derived score is shown, never their figure.
