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 pokemontcg.io (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.
