I have a few error cards, I'm not sure if these are rarer than the corrected version, or if some of these were even corrected, but here's a short list:
Vulpix Base Set (Says "HP 50" instead of "50 HP")
Diglett Base Set (The energy symbol for it's first attack is sideways)
Seaking Jungle (Says "Put Seaking on the Stage 1 card" instead of Put Seaking on the Basic Pokemon")
Dark Arbok Team Rocket (Says copyright 1999-23000)
Dark Vileplume Team Rocket (Has weakness to Fighting instead of weakness to Fire)
Miscut cards aren't as cool IMO because they're not that uncommon, off the top of my head I have,
Miscut: Baltoy SV, Azelf LA (LP), 2x Computer Error Promo, Dome Fossil, etc...
That's what I have that I could think of and could find.
