Hi Christopher, I did not personally purchase them, they belonged to a now deceased family member. They were definitely not an expert in baseball collecting, more of a temporary hobby, and I'm afraid they were likely duped many times.
I knew nothing about baseball collecting prior to acquiring this collection, but have learned a few things thanks to online research so far. I have suspicions that many of the balls are likely forgeries but wanted to be sure. This website and forum seems to me like a reliable source of opinions and wealth of knowledge from what I have gleaned so far.
