Beanie Babies, produced by Ty Inc., can be sold locally at garage sales and flea markets or by placing classified advertisements in local newspapers. Beanie Babies can also be sold on websites that allow private-party sales, such as such as eBay, Amazon or Bonanza.

Some social media websites, such as Facebook, Google Plus and Reddit, have numerous private and public groups that focus on buying and selling collectible items. To make an online listing, include clear pictures of the Beanie Babies and identifying information about each toy, including its name and production year. As of 2014, Ty Inc. has created more than 800 types of Beanie Babies since the line launched in 1993. Several of the discontinued designs are considered highly collectible.
