Listed here are some sports card sites I regularly visit
Incredibly informative site on vintage sports cards, especially pre-war baseball.
I am a sometimes contributor to this site run by Indiana television news guy Rich Mueller. On this site you'll find news and features about vintage and modern sports cards and collectibles.
I used to buy cards on this site but over the years they have changed the site and I find it too confusing now to find and purchase cards. There are all sorts of collecting resources here, though largely for the modern collector. I regularly visit this site for the show calendar which is the best list on the Internet for card shows.
Great images of baseball card wrappers going back to the early 1900s.
All sorts of great info on Red Man tobacco cards. I think the coolest things are the photos of the hats you could win if you sent in 50 tabs.
This is the website for Champaign, Illinois, vintage sports card dealer Tony Schaefer. Tony sets up monthly at the St. Louis card show at Orlando's. He is also a regular at the National and occasionally hits some other Midwestern shows. Like me, he regularly blogs about the shows he attends. He is a great writer and his blogs are always entertaining. As far as card-show dealers go, Tony has the best vintage inventory in Illinois.
Insightful and interesting autograph blog written by author and long-time autograph collector Tom Owens. There is a lot of great insight here on sending for autographs through the mail. Tom also provides some great stories on his pursuit of autographs.
I am fairly certain that the Wisconsin Sports Collectors Association is the oldest sports collectors club in the country. The club was founded in 1975 with many original members and their children still active in the club. This non-profit group puts on the monthly Gonzaga show in Milwaukee which is about the best show around. There are always 90 to 100 dealers. A large crowd. A live auction. A kids auction. Most shows have an autograph guest with a charge around $5. There is food, including fresh-baked cake. Keith Kilps, whose father was a founding member, is the current president of the club. Under Keith's leadership, the club raises a great deal of funds for local charities. You'll be hard-pressed to find a better guy around than Keith. He goes the extra mile to make sure dealers and customers have a great time. I can't say enough about Keith and the WSCA. I look forward to each and every WSCA show which are can't miss events for sports card collectors.
This is the website for Blow Out Cards, a company that sells cheap wax. They have an excellent collector's forum with great info on card shows and a card shop locator.
Website that lists card shows in USA and Canada. They are kind enough to list my monthly show in Milwaukee.
