You are showing 3 different versions of a similar chip. Meanwhile, TCR lists 9 different versions, some of which are errors. To complicate matters, some of the 9 are "light grey" and some are "dark grey". And then, there is only one listing that includes the notation "incused" but you are showing 2 different incused chips.

Since not all scanners are equal and no two monitors are the same and no two people seem to see shades the same way and your scans are not that very detailed....

So, to say the least, I think people are struggling to determine value (which can range from D - M) because they cannot conclusively tell what 3 versions you have there.

Do you know the associated TCR numbers for each chip?
