This is "Lego Wookiee Chewbacca Mini Figure Star Wars 2000" This is authentic and markings can be seen in pictures. It's telling me this piece was from around 2000, but i get the feeling the AI is confused and this was from a set around 2009-2011 from all the sets it was found in. I could be wrong though

Either way: authentic. Condition can be seen in pictures. No damage or issues.
