I would say all will be graded 8 or less, there are also scratches on the holo foils. I think most of them would be looking around 7-8 range but as Gary said there is so much you might not be able to see in these pictures. Maybe the seller would take photos with a flash on the camera? Sometimes this can highlight scratches you can’t see normally.
Prices can differ a fair bit looking on ebay sold listings you could be talking anywhere from £45 to £130 depending on the card and the grade it receives. (if the cards don’t receive less than a 6 or more than a 8)
I can see the scratches on the holo pretty clearly on my phone, and what I identify as some moderate surface wear as well. Magenton & Raichu are both in the 6 range, and Alakazam and ninetales have a little higher chance of grade 7.
Base 1st edition holos are the exception in that only PSA grade 6 and under equate roughly that of the raw value, whereas collectors of almost all other sets typically seek 9 or higher.
So yes it would be better financially speaking to sell as raw cards. They all fall within the $50-$90 range in a general retail environment.
