Here is some info on these two! The beanie on the left is the WDW 2003 Adult Simba beanie, part of the 2003 WDW lion king beanie collection including; Sarabi, Mufasa, Nala Simba and Scar. (The Sarabi is a very rare and highly sought after plush) This one is very commonly mistaken for the extremely rare WDW Mufasa (Here is a photo of the 5 plushies from my collection [link]) Because he is very rarely seen The one on the right is the WDW 2011 Adult Simba plush, He was sold alongside a Scar beanie. Both were released to celebrate the Lion King Bluray release.
I hope this helps! A great addition to your collection, well done!
