CertCheck for Chrome Extension

CertCheck - A quick lookup utility for graded card certificate information - PSA, CGC, and PGS slabs are currently supported.

Before purchasing your next graded card on sites like eBay, PWCC, or Heritage Auctions, you'll likely want to pull up the official certificate details. For PSA slabs, you can find direct links to the population reports for that card and it will sometimes include previous public sale history of the card. This also helps you validate all the details about the card you're about to spend hard-earned money on.

CertCheck makes it easy to look up the certificate details for cards in your collection or cards you're thinking about purchasing, and it works across different grading companies too in case you trade in multiple kinds of slabs.

★ How to Use:

Enter the certificate number of the graded card that you'd like to search, then select the radio button corresponding to the slab's grading company. Click the search button to initiate, and the extension should open the webpage for the certificate details.

★ Grading Companies Supported:

CertCheck supports cards that are graded and authenticated by the following grading companies.

- CGC - Certified Guaranty Company
- PSA - Professional Sports Authenticator
- PGS - Platin Grading Services

★ Types of Cards Supported:

CertCheck works for all different types of cards. As long as a slab is graded by a supported company, it's details can be searched by CertCheck. This works across a variety of collectible card games / trading card games such as the following:

- Pokemon cards
- Yugioh cards
