While they’ve diminished in value — a Beanie Baby worth $900 in 2001 might be worth $300 now — they can still fetch a pretty penny in today’s market, especially if they are prototypes, Employee Bears, limited releases, first generations, “crazy oddities,” or ones signed by Warner himself.

In the 2000s, Warner maximized the rarity and thus worth of his Beanies by only manufacturing 300 versions of particular plushies, like the Billionaire Bear.

In recent years, Dennis has noticed a spike in the number of high-value Beanies being listed on the market or auctioned off online.

He thinks it’s because collectors, namely “executives” who’ve received special Beanies, are dying and their family members are selling or donating their belongings. Bidding results are usually the result when this happens, as high-end collectors vie to snap up the rare and seldom seen Beanies.

Dennis believes that if you’ve got a bag of them laying around, now might be the time to sell them before they lose any more value.

“It might be best for people to sell them now instead of hold on to them,” he said. “I think things are kind of where they’re going to be. I don’t see their value increasing in the future, especially for the more common ones that are 99 percent of what’s out there.”
