Star Wars Action Figures In A Time Capsule?

7/5/2018 Lucasfilm George Lucas Star Wars Figures

Lucasfilm posted a fun story on their Facebook page a few days ago going into the July 4th weekend. 

"36 years ago this weekend, at Lucasfilm’s annual July 4th picnic in 1981, a time capsule was buried within the cornerstone of the Main House at Skywalker Ranch containing a bottle of Skywalker Ranch wine, various paperweights, Star Wars action figures, and the contract with Universal for American Graffiti and “an unnamed science fiction movie”, among other items."

Looks like the figures included in the time capsule were Han Solo, Darth Vader, Yoda, Luke Skywalker, C-3PO, Chewbacca and a Japanese Takara wind-up R2-D2! What conditions could those figures be in now?
