I hate to see this thread go dormant for nearly 2 months!
Finally found this guy after 15-20 years of looking. Of the KNOWN Giants PM-10s, I still need Haller, Pagan, Pierce and McCormick. Although I've never seen one, I think there may be a pin of Jack Sanford out there. It's crazy how readily available most of the Mays pins are while guys like Gabrielson are basically impossible. I get that the Mayses outsold everything else but you would think that, at 50 cents per pin, many kids would collect the whole team in the course of the summer. The Pagan is so rare I never even knew it existed until a few months ago. I love these things!
