Expanded Format High value cards

Hi All, My question is about the expanded format english cards. From black and white to the end of the xy block. What cards have a high value currently besides the following? Mainly talking about the pokemon not trainers or special energies. Commons, uncommons, or even rares.
Ignoring any full art, ex or secret rare cards. The following are the cards I can think of.
any bw or xy zorua or zoroark.
dark explorers- dark patch
several sableye
several sneasel and weaville

Off the top of my head; expanded lives on the Ace-spec trainer ‘computer search’ (137/149)

It’s only a one-off in decks so a player only needs to aquire 1, but they still go for good money

Thanks but I consider the ace specs ultra or secret rares (1or 2 per box back in the day). And my dumb self may have traded away my 2nd computer search and 2nd dowsing machine. Im asking which commons/uncommon monsters stand out above others in value (and expanded playability). same for rares and holos.

Hypnotoxic laser and that one stadium that increased poison damage (virbank, or Viridian city gym …something like that), deluge blastoise, the broken exeggcute, in xy there was parallel city, octillery, that one gallade with premonition, battle compressor, vs seeker

You can always just search the winning decks from those years and judge from there

Oops didn’t see the no trainers part. I’ll leave this untouched though.
