I have several player collections as listed in my sig below but the one I cherish most is my Billy Pierce collection. I sent him this pic of what I could fit on the table a few years before he passed away. I've added some items to it in the ensuing years but most of those are display pieces, publications and various photos, mostly Type I's.
Of his career-era cards I lack only his '59 Bazooka SP. I keep bidding on it and maybe someday I'll get lucky. His Shirriff coin from 1962 is also on my wantlist but it hardly ever shows up anywhere for sale/auction and it's an identical, more costly version to the Salada coin so I'm not really chasing it.
I have a PM 10 stadium-sold pinback button on my list but I've never seen evidence that one really exists.
Here's a link to an old blog post of mine with my Billy Pierce checklist, haphazardly updated over time.
