The most important things when shipping baseball cards are using the proper packaging materials and choosing a reliable shipping method. Baseball cards can be damaged easily during transit if not packed correctly, so taking the time to package them securely is crucial.
I recommend using a rigid card boards like a trading card storage box or penny sleeve pages sealed inside an envelope or small box. Cardboard is sturdier than just an envelope and will protect the cards from being bent or crushed. Make sure to use new cardboard and not recycled which can be lower quality.
You’ll want to sandwich the cardboard containing the cards between two layers of bubble wrap or air pillows for extra protection from impact. Bubble wrap is most effective as it will cushion the cards if the package is dropped or handled roughly during shipping. Use enough bubble wrap or air pillows to completely cover the cardboard on all sides with at least an inch of padding.
Seal the cardboard encased in bubble wrap inside a mailing envelope, small padded envelope, or rigid shipping box based on the number of cards. Do not overstuff envelopes as it makes them more prone to bursting open during transit. For larger collections, a small rigid box is best. Try to avoid using flimsy envelopes alone without extra reinforcement.
I’d recommend taping the seal on envelopes and any seams/openings on boxes multiple times with clear packing tape for additional security. Run tape around the entire perimeter and then tape a giant X across the closure for reinforcement. The goal is to make openings impossible to open without cutting the tape.
Clearly write the address of who you’re shipping to as the recipient and your return address as the sender on the exterior of the package. Include your phone number as well in case there are any issues. I also advise including a shipping invoice or note describing the contents as “baseball cards” for clarity.
Consider insuring the package especially if the cards contain valuable autographs or rare vintage pieces. Insurance will cover you if the shipment gets lost or damaged in transit. The post office provides insurance, and private carriers like UPS and FedEx offer insurance plans as well.
As for shipping methods, I always go with a trackable service like USPS Priority Mail, UPS Ground, or FedEx Ground for baseball cards. Tracking provides proof of delivery and helps locate lost packages. Avoid regular first class mail without tracking as it offers no visibility or recourse if problems arise.
Priority Mail from USPS has been reliable in my experience and offers $50-$100 of insurance included automatically. UPS and FedEx Ground are a bit faster for most areas but may cost a few dollars more. Avoid Parcel Select as it has no insurance or tracking added. International shipments require extra documentation and customs forms to send baseball cards.
Proper packaging and choosing a trackable carrier will give your baseball cards the best chance of arriving safely at their destination. Take your time packing, get tracking, and insure valuable items. Following these tips should result in smooth shipping experiences for your baseball card collections.
