Great review! PCGS has been quite good to me with only $15/item to grade. I plan for longer turnaround times on all services and orders so I don't mind waiting for what I regard to be the highest quality grading service. Maybe not the fastest but PCGS slabbed items turn heads. Not to say that NGC doesn't, just a matter of style and preferences.
Thanks!
I love PCGS personally for the same reasons listed. Although, the cost to grade physical cryptocurrency through PCGS has significantly increased, and the once-available option of $15 per item is no longer offered. At least not to my knowledge.
