I agree 100% with what you say, but have issues with the TPGs who won't call a spade a spade. If a coin is hairlined from cleaning, then call it hairlined. If a coin has been polished to death, then call it polished. If a coin has been cleaned without damaging the surfaces then it has still been cleaned. Just be honest, that's all I'm saying. After all, they offer a cleaning service in all but name. They also seem happy enough to slab coins that have been dipped, and more than the odd repaired coin has passed the audition.
