Based on those descriptions both of those varieties fall into the stand "IC CHIP" rate which is $7.50 per pound which would be approx $16.50 per kilogram,

"Flatpacks" or bga chips are priced differently, they by definition don't have legs, instead connecting to the board by flat pads on the underside surface

But Quad Flatpack Chips and Ram Chips definetly have more gold than standart Ic chips (2 side long metal legs)

They should have a different price

Gold is only one of the qualities looked at. And there is so little gold in most ICs if any type that it is not really what makes a classification.
AMD K5 and K6 series ceramic chips have far more gold than pentium ceramics. It’s all the materials that make up a chip.

So 1kg=2,2lb of gold finger RAM cost almost $46,20(boardsort.com price)

1kg of RAM is equal to: (approximately)

-clean gold fingers 70gr=0,15lb=$6.80 -$7.15 (boardsort.com price)
-MLC`C - 10gr = $0
-Resistor Networks(RN) = 6/7gr = $0
-Blank Boards = 0,530gr = 1,17lb = $3 (boardsort.com price)
----IC chips = 380gr=0,84lb= which must cost the rest of the price
(around $35!!!)

Please take note that the numbers can vary a little.I made personal experiment for 1 kg of RAM and 5 kG of RAM .Chips were between 380gr-450gr per kilo of RAM.Clean gold fingers were always 70-75gr per kilo of RAM

Ofcourse, everything is approximetly depending kind of RAM but vast majority of the price for GOLD FINGER RAM must come to thew chips

So in conclussion , fingers and blank boards make around 25% of the price.Capacitors are magnetic so they are worthless, as well as the resistors so In my opinion these Ic chips must cost a lot more
Please correct me if I make some mistake

I’m not following what it is you are asking.
The prices are based on a combination of experience, value, and changing markets.

Generic classes like ICs, flat packs with or without tabs... the products are inconsistent. Motorola, Samsung, DEC, they’re all different. So the rates average the value.

The way I understand what Kiromana is trying to say is that the price for just IC's is way lower than the price for ICs that are on a ram stick.

If you sold mixed IC's to boardsort they are $16.50 per kilo.

However when you break down gold ram Boardsort is paying as much as $35.00 per kilo for IC's that came off gold ram.

However I could be misunderstanding him myself.

The ICs on ram sticks are known quality and value.
This is part of why many of use beyond Chris have pointed out not to depopulate. You almost always loose on the process.
If you stripped a ram stick you’d have blank ram and random ICs.

It’s a known range of value situation.
