Can you give me a link to some cards where that is happening?  I definitely want to look into that.

We ignore the "brand new" for games on eBay but will include it if the item says "Brand New" or "Sealed" or something similar in the title.  If the price is really low, we will usually toss those sales out instead of adding them into the data but some do still squeak through.  It isn't always obvious where the cutoff should be on "too cheap" and without understanding images (which our AI doesn't do at this time) it is hard to kick out the correct items with 100% accuracy.

What do you mean?  Can you give more some more details about what you are wanting?

You should check out PSA or Beckett websites to find the cost of these services.  We do not grade or authentic items.
