I’ve been building a 1st Ed Base PSA 9 holo set, and I’ve noticed the vast majority of available 9s are from the 2xx cert era or lower ( not that it’s a bad thing, I love getting the 2xx cert discount when collectors care too much about the serial #). I was thinking about it, and I assume this is because most of 1st Ed base was graded 5-10+ years ago and there has been extremely limited sealed or raw mint cards pop up over the years.
Are there any other insights to this? I know gary graded a ton of it way back, but I would be interested to hear any thoughts on this.
I looked at the PSA 9 1st ed stoise as an example and it’s PSA 9 pop only really increases by 70~ copies per year since 2018/19
