You are greatly overstating the quality of ultra moderns. They certainly are a higher quality than older coins overall, but none of the ultra moderns come out "almost all perfect" like you say in the video and that includes the ones whose population reports are almost all 70s. Many of the big submitters only have the 70s slabbed so if they send in 2k coins and get 650 70s thats all the gets recorded in the population report making it look like they're all basically perfect when over half of them were rejected. Then with collectors and smaller submissions they will do a quality control check and not submit the dogs if you will so it's already skewed towards the highest quality of the run. Business strikes are even less quality
