I joined the forum Net54 earlier this year, because I thought it would be cool to learn more about pre-war cards, and get to see all the other members' great collections. And dream of when I'll have a collection close to some of theirs. That's worked pretty well, but I've also found you can get some good deals for buying too. One member holds weekly auctions of lots of 1950s and 1960s cards, and I made a couple of purchases from him.
One was an 8 card lot of 1955 Bowman, including three high numbers which I got for $19. Before buying this, I had just three 1955 Bowman cards, so it was definitely time to get some more.
