Valuable uncommons/non-holos?

Hi everyone, recently realised that the uncommon rocket’s admin card fetches a sizeable sum and was wondering why that is so. Are there any other non-holos/uncommons that fetch a pretty penny? Thank you all for your input in advance!

My guess is that it’s a powerful card in legacy decks. Others that come to mind are Oracle, Holon Transceiver, and Call Energy, but I’m sure there are many more.
