If there are only two of something, and twenty-seven more are added, the two are going to take a big hit.
27 at 100-350K each is nothing to sneeze at, but I don’t think there will be 27 people ponying up a million plus, and many of those who might will figure out that they don’t need to.
The OPC cards from that era are poorly cut and printed on lesser card stock, so it is very difficult to pull a card that would be graded a 10. That's why there are only two with that grade. It's unlikely that there will be more than 1 or 2 cards that could be 10 candidates from this case.
