Agree, not sure if the lonely IC and tantalum could get you a bump with the damage already done.

There's no visible gold I can see of anywhere on these boards. They had 1.5lb. aluminum heat sinks each board.

That’s midgrade.

Two layer copper board with no ICs. Heavy depopulation.

Lost,inlodos, I have waited five years to tell you you are wrong...maybe. I have been cleaning crypto antminer hash boards, probably about 2000 of them. I don't wear a hat, so I am not talking thru my hat, but Chris said the hashboards with heatsinks (I'll post photo on both sides would classify as midgrade. With the heatsinks removed, he said the price would be considerably more, but still less than peripheral low grade.
One side has the chrome colored heatsinks soldered onto thebut there grid pattern in the oblong sections. The other side has a larger heat sink, bright aluminum color, and it is attached to a small black plastic chip. Sometimes the chip stays attached to the board, sometimes the top plastic layer is ripped off exposing the precious metal content, and often, the heatsink with the chip attached is ripped from the board, tearing the copper layer. The reverse usually pops the sink off, leaving the solder coating, but having the grid lines implied. So any of the boards having one side covered with the little black rectangles is still full populated, chip wise.
Now those boards that have major tiny chip removal (there are 60 on one side of the boards I have) or even partial chip removal, I have no idea if Chris' quote will stand. There are no exposed gold pins, but there is lots of tiny gold rimmed circles and dots. Plus some of the grids where the sink/chip is missing has the gold plating showing. If a person only has a few boards they may get tossed into midgrade, but with several pounds or hundreds of pounds, they will get a closer look. And then again, when Chris gets a closer look at my "clean" boards, he may agree with you.

Bullshit, Austin86. I suggest you actually get a hashboard and look at it before you show your ignorance. Nothing has been removed intentionally except the heat sinks on each side. The only "population" is the tiny ic under the heat sinks, which is a paper thin plastic casing. there are five tiny aluminum capacitors by the connector. The back side had the heat sink soldered directly to the board.

Removing heat sinks is not considered depopulating, especially when advised to do so by the Buyer at Large.

it is if you are pulling the chips with the heat sinks... both you an OP posted photos of boards with the ICs pulled off, we can all see this and we all know what you did, you can't hide it and getting all pissy and name calling dose not help you case. Go right ahead, send them in as something higher then mid/low grade board, I dare you to. You are just a troll or a dumbass or more likely both. blocked.
