Here's a comprehensive database of third party coin grading services or TPGS. Only four grading services are trusted and actually increase the value of a coin and they're PCGS, NGC, ANACS and ICG. The fact is, most dealers, numismatists and experts accept NGC and PCGS as the most consistent and reputable services.





When you look for ultra-rare coins, coins that trade for thousands, hundreds of thousands or even millions of dollars they're are always graded by either PCGS or NGC. There's a reason that they're chosen to authenticate, certify and grade the most valuable coins on the market. It's because they're the best, no matter the claims of other TPGS or dealers or ebay coin sellers.
