Hockey Card Collecting, Breaking, and Investing

My name is Griffin, and I run Mainely Hockey Cards! I've been collecting for over 15 years, and really started taking investing in and flipping hockey cards seriously in the past few years. It was always a side hustle for me, but as the pandemic hit, things started to change, and now we’re here!
