About CardVault
A price checker built for collectors who want real sold data, not estimates.
What is CardVault?
CardVault answers one question: what is this card worth? It covers 100+ iconic sports cards across baseball, basketball, football, and hockey — from 1909 T206 Honus Wagner to 2023 Victor Wembanyama rookies — plus live Pokémon TCG pricing pulled directly from the official Pokémon TCG API.
Every price on this site is sourced from real sold transactions and links back to the source so you can verify it yourself. This is what Beckett, 130Point, and Card Ladder do — show the work.
Data Sources & Methodology
TransparentPokémon TCG — Live TCGPlayer Data
All Pokémon card data and prices come directly from the Pokémon TCG API (pokemontcg.io), which sources pricing from TCGPlayer's live marketplace. Prices reflect actual recent transactions on TCGPlayer — not estimates. Each variant (Holofoil, Reverse Holofoil, 1st Edition, Normal) is shown separately with low, mid, market, and high prices.
Data is refreshed hourly. When you see a price on a Pokémon card page, it is the TCGPlayer market price as of that refresh — the same number you'd see on TCGPlayer.com.
Limitation: API coverage is complete for sets from Base Set (1999) through current releases. Some promos and regional exclusives may show no price data if TCGPlayer does not have listings.
Sports Cards — Public Auction Records
Sports card values are compiled from publicly reported sold results across:
- ✓eBay sold listings — Primary comp source for mid-grade cards. Filtered to completed sales with PSA/BGS/SGC grades specified.
- ✓Heritage Auctions — Public auction results for high-value vintage and modern investment-grade cards.
- ✓Goldin Auctions — Auction records for premium modern and vintage sports cards.
- ✓PWCC Marketplace — Consignment auction results for high-grade examples across all sports.
Grade-by-grade pricing tables on each card page show the estimated market value at each PSA grade tier based on the above sources. Each table includes a direct “Verify on eBay” link that opens a pre-filtered eBay sold search for that exact card so you can confirm the data yourself.
Limitation: Sports card prices are curated manually and updated periodically. The market moves fast — for real-time pricing, always verify via the eBay sold links on each card page. Values shown are the mid-point of a reasonable range based on recent comps, not a guaranteed price.
PSA Population Data
PSA population figures (total graded, PSA 10 count, PSA 9 count, gem rate) are sourced from PSA's publicly available population reports. These figures are used to contextualize grade pricing — a card with a 0.5% gem rate commands a higher PSA 10 premium than one with a 15% gem rate.
Population data is a snapshot and grows over time as more copies are submitted. The gem rate shown reflects the population as of the last manual update for each card.
What We Don't Do
- ✓We don't sell cards or take commissions on sales
- ✓We don't promote specific sellers or grading companies
- ✓We don't fabricate scarcity or hype specific cards
- ✓We don't claim our price estimates are definitive — they're starting points backed by real comp data
- ✓We don't hide our sources — every price has a "Verify on eBay" or "Buy on TCGPlayer" link
Understanding Card Grades
Gem Mint
Perfect centering, sharp corners, no print defects. Extremely rare. Commands massive premiums — often 5–20x the PSA 8 price.
Mint / Near Mint-Mint
Near-perfect condition with minor imperfections under magnification. The sweet spot for most collectors balancing quality and availability.
Near Mint–Mint
Slight wear on corners or edges, good centering. Most commonly available graded condition. Solid middle-market prices.
Near Mint
Light corner wear, minor print lines visible. Still collectible, significant discount to higher grades.
Excellent or lower
Noticeable wear. Value primarily driven by rarity of the specific card, not grade premiums.
