Another word of advice....when everyone is saying the same items are guaranteed to go up....they already have, and smart money is getting out.

For decades low-mid grade t206s and 33 goudeys littered auction houses. They were likely the most collect and printed cards of the prewar era. Couple that with people saving everything of the superstars of the day, newpapers, photos, etc and you have a big supply. Demand is always the other side of the coin, but the supply side is only curtailed when people want to hang onto their items.
