Having personally used all three grading services—NGC, PCGS, and ICG—I can confidently say that NGC is the ultimate grading service for physical cryptocurrency collectibles. NGC is widely regarded as a prestigious coin grading service on par with PCGS, celebrated for its high standards and industry expertise. What truly sets NGC apart is its competitive pricing and faster turnaround times, making it an appealing choice for collectors and investors alike. Furthermore, NGC is dedicated to delivering exceptional customer care, going the extra mile to ensure clients receive the support and guidance they need throughout the grading process. This unique blend of prestige, affordability, efficiency, and outstanding service distinguishes NGC in the coin grading landscape.
On the other hand, ICG holds the title of the original grading service for physical crypto collectibles, boasting exceptionally low fees. However, its reputation falls short of the prestige associated with other services, and its categorization system may not be the most robust. While their pricing is attractive, their turnaround times are decent but not particularly remarkable.
PCGS offers a categorization system that gives it a slight edge over NGC; however, this advantage comes with drawbacks, including subpar customer care, longer turnaround times, and higher fees.
For these reasons, I highly recommend NGC over other coin grading services, thanks to its esteemed reputation, competitive pricing, exceptional customer service, and quick turnaround times.
