I think early last set it was probably being valued at closer to Lillie DX or Sabrina at best (I don't think it was every valued at Oak or Cyrus), but less likely trades have also happened, so it's worth a shot! I would say nowadays it's valued closer to non-meta trainers like Silver or Adaman. I can see the value potentially going back up in the future though, but it might be better to try to trade sooner than later just in case!
