List of 3rd Party Grading Companies
Hello and welcome to NerdMelon's Most Comprehensive Guide to 3rd Party Grading Companies on the Net (Including images, sales data, website links, and more!)
The table below represents every 3rd Party Grading Company found in our database. We've sorted through millions of records and compiled a list of every grading company we could find. Every new grading company we come across will be added to this list, and the list is updated weekly. That said, there are still many companies out there that havent yet shown up at one of the auction houses, so this list is by no means complete. We hope you find this article useful when buying that next Holy Grail or choosing a company to grade it.
And if you're interested in how these companies stack up against each other, we have our 2021 Market Share Analysis of 3rd Party Grading Companies.
