Is the foil worth pulling?
Before you list a stack, know which foils and reverse-holos are worth separating out. Drop in a card and Foilio shows the normal vs foil reference price and whether the premium justifies its own listing.
Why it matters for sellers
On a low-value common the foil premium rarely covers a separate listing's effort and fees, bulk it. But on a chase card a foil can be worth multiples of the normal, and burying it in a lot leaves money on the table. Working out your real take-home? Run the eBay fee calculator or build a fee-aware buylist.
Reference estimates, not appraisals or financial advice. Foilio is an unofficial fan project, prices are independent reference figures from free catalog APIs.
Questions, answered
What does the foil premium tell me?+
It compares a card's normal price to its foil (Magic) or reverse-holo (Pokémon) reference price, as a percentage. A big premium on a non-trivial card means the foil is worth pulling out and listing on its own; a small premium means it's fine to sell with the normal copies.
Where do the prices come from?+
Honest reference prices only, Cardmarket EUR via TCGdex (normal trend vs reverse-holo trend) for Pokémon, and Scryfall (eur vs eur_foil) for Magic. Never sold, scraped, or marketplace-listing data.
Why only Pokémon and Magic?+
Those have a clean, free normal-vs-foil price split. Yu-Gi-Oh doesn't expose a reliable free foil-vs-normal reference, so it's left out rather than guessed.
Is it exact?+
It's a reference estimate from the highest-value printing of that name. The specific set, finish, and condition move real prices a lot, always verify the exact card before listing. It's free and runs in your browser.
