I think you're looking at a different type of grader than the services I'm referring to. You're paying for the grading/encapsulation as a service, independent from any future sale plans, so they have no stake in under or over-grading any individual coin. They got their service charge (typically $15-100 or so depending on estimated value and turnaround speed) and they'd lose community trust if they were consistently too lenient. The market only trusts a handful of firms, most of who have been around since the 1980s or 1990s and certified millions of coins. Most other brands are "price it as you would an uncertified coin, caveat emptor" or perhaps even worse, as some sketchy dealers would set up a fourth rate grading service as a means to make low-quality inventory more appealing.
