Actually each collectible grading service is a separate company/legal entity in its own right. CU is the parent corporation and owns all of them, but is legally a separate entity in its own right. Legally, they're not "all one in the same." Except the modern market is largely dead with a few exceptions. Many coins have lost 60+% of their former highs with no signs of recovery. PCGS has been grading for 33 years now. Exactly how many quality coins worthy of grading do you think are out there? As greed and TPG generated grade inflation push prices even lower, the number of coins worth certifying is declining not even accounting for examples lost through attrition. Even hoard/bag coins for common dates need to be MS66 or MS67 to be worth even considering to potentially submit. An uber common MS67 Morgan can almost squeeze into the economy tier and might one day if prices continue to drop. Thank heaven for grade inflation and gimmicks to keep the services a float. If things continue as they have for the last 10 years, you'll be seeing bankruptcy filings in the future.
