I removed the shielding from those. Do I need to do that?

Gold finger card with bracket exactly as pictured
Remove the frame steel for without bracket.

Lost, here is another procedural question, a what if scenario. As I frequently mention, I prefer to deliver my boards in person rather than shipping, so weight or bulk is not a problem to consider.
Now that there is the no bracket finger card class, which if one were mailing, one should definitely remove the excess iron weight, but is it to my advantage to remove the bracket from the cards I am delivering. Again, it is not a question of time involved or much of anything else, except for the top dollar. My assumption is that 100 cards without the bracket at a slightly higher price per pound is pretty much the same as the same one hundred boards with the bracket at a slightly higher poundage at a lower rate.
Now that I have instigated a query, I will admit that sometime in the next day or so, I will do some precision weighing of bracket cards and then remove the brackets from the same group, and calculate the final payout;. Thats just the way I usually do something. Think about it, ask questions, think some more, and finally just do it to confirm the speculation.

I was justing doing maths regarding some boards graded as periph, on a sample desoldering they were 46% ic chips by weight


So for this scenario, right now (3/29) w/ bracket is 3.85 a lb , no bracket 4.00

So there needs to be 96.75% of original weight in no bracket, or less than 3.25% bracket by weight.

That doesn't account for selling the steel bracket but steel just hit 2¢ a lb around here so that's negligible

There’s more original weight without the bracket than that in MOST cases.
Remember we’re generally talking about CONSUMER computer cards. Not server cards. So a bracket is the thin steel or aluminium strip of metal us use to fasten the board to the case for both grounding and vibration reduction. It fights gravity as well but that’s not really the idea in the original design.

Server equipment usually has heavier brackets. And too often they’re soldered or riveted to the board. I’ve use trimming nips to cut some of these off in the past to stay in the GFC class since the steel brackets weigh as much as the board. So server brackets that are heavy like that need to be removed in general. Old scale and new one. These default to peripheral at the high end with the brackets on.

Mounts, thick heavy (4oz+) steel, plastic, etc brackets. like you commonly see on hot-swap cards must be removed or it’s peripheral grade for your board at best. Some high impact carbon polymer mounts get to over a pound in weight!

Trays must also be removed. Regardless of what is attached to it an aluminium tray will net you midgrade and a steel tray will put you at low or worse. Steel will likely put you into a low end breakage class.

Out of curiosity I grabbed a few of the "average-est" PC gfcs I had, and removing the brackets (and screws) removed 32,22, and 45% of their weights, the higher figure was a Linksys network card

Lol.
Obviously it depends on the size and population of the card
I forgot sometimes about things like NICs and modems. Removing the bracket from a video card, a SAS controller etc, however will make almost no difference at all. Removing the bracket from a PCIx SSD would probably remove 75% of the weight or more.
So there’s obvious cases.

That said sending in 20 fax modems with brackets and 50 video cards without probably would be frowned upon.
I doubt anyone at boardsort would say anything but I am not boardsort so I will: that’s just rude. Profit maximising but still rude.

;)

Just to double-double check. These are WLAN cards from laptop. Removing shielding AND the leftover steel structure (some left on in the pic) will result in GFC without bracket rate?
