4) Midgrade
5) Peripheral

1 is borderline. But given the low quality PCB I see it going as midgrade.
The 677 packages use silver bonding with silveride etch and connectors. The solder is lead and tin. Despite the copper weight the majority is in steel and PCB. The long nickel pins are the best thing on the board weight to value wise.

It could still get an upgrade. But I wouldn’t place it in peripheral.
Midgrade
