I was at the Twins game in 2022 when they retired #36 for Jim Kaat. The team was able to get special baseballs for that game and I was fortunate to purchase a game used one, as well as a couple unused ones, for my collection. Tom O (orr23mj on SCN) offered up a couple Christmas deals and one of them was one of those baseballs already signed and inscribed with “#36 Retired 7/16/22” and I bought it. It was cheaper than if I got one of my own signed with postage and the autograph fee, etc. I am waiting to get the game used one signed exactly the same way.
