I have been toying with the idea of sending in some NGC graded IKE's to either CAC, PQ check or I see this other service called MAC. I tried to do a web search on them but haven't found a thing about them, anyone have a link to their website? Anyone with any history with PQ or MAC?
The only two grade verification services that I would consider would be CAC or Eagle eye. I would also put a very slight premium on Ricks ECC for modern proof coins. Everything else would be just another sticker on a slab to me.
QA-check, not PQ-check. The person who runs this, James Sego, is The Guy for Ikes. http://qacoins.com/
The grader for the MAC service is the Accugrade guy. This should tell you everything you need to know. Draw your own conclusions.
