Hello everyone!

I am not very knowledgeable when it comes to nendos, so I came here to ask a question

I have this Pokemon Center Exclusive Lively Lullie (photo taken from online, but it looks like this) new in box still. I am trying to keep up with the values of all my nendo in a chart. However, I cannot find anything for what she is going for. What would be the best way to check that out?

I have sent plenty of Japanese ones, but nothing from Pokémon Center itself. Any and all suggestions would be lovely. Thank you again!
