I’ve been collecting cards, autographs and memorabilia for 35 years. This is the single most impressive autographed accomplishment I’ve ever seen! GrandslamCollectiables on IG has completed the in-person authenticated autographs of all 330+ on-card baseball autographs - spanning more than a decade of baseballs best players. It took two people 23+ years to complete this set! Truly amazing and magical! (Posted here with permission). Just….WOW! They even got all the checklists signed by the artist, Dick Perez!

Welcome to the Autograph Collecting Mantel Group! This group is all about the ink—whether you’re collecting on-card autos, signed memorabilia, or chasing in-person and mail-in autographs, you’ve found your people. From fresh-pulled rookie autos to vintage legends with the cleanest pen game, this is the spot to share, learn, and connect. Our goal is to build a fun, welcoming space for collectors at every level. Share your latest pickups, ask for authentication tips, talk through mail-in successes (and fails), and drop info on upcoming signings—both in-person and TTM (through the mail). You’ll find hobby news, signing announcements, mail day highlights, and plenty of discussion around pen types, photo choices, prep strategies, and more. We’re here for the stories behind the signatures just as much as the items themselves. Whether you’re a binder-builder, a slab-chaser, or just love getting a Sharpie in front of your favorite athlete—this group’s for you. Let’s keep things respectful, helpful, and collector-driven.
