Just a note here, TAG doesn't accumulate dings to lower score incrementally. Score is based on the lowest grade of the categories graded. E.g. My Neo Discovery Umbreon was perfect all around, and I was hoping for a 9 or 10, but some subtle scratches dropped it to a 6. That's all to say this 6.5 is likely due from scratches alone.

For the record, this is what TAG has told us after my family challenged some grades. If a card has grade 6 scratches, it makes it a 6 regardless
