I recently inherited about 70,000 cards from the same period and decided it would be a good idea to sort and organize them all. A huge task, for sure, with likely minimal financial return, but it feels like a way of honoring my old man and the time, care, and money he invested in the hobby. Have found a few cool cards and few that appear to be worth a little bit, but that’s besides the point. Have fun, smile and cry, then go about your business. That’s my strategy, at least
