I get what you're saying .
If all six have gold spreaders then gold cap board is correct.
Though these CPUs are normally a chrom/nickel plating on a brass spreader. So you may want to etch or scratch one cap to make sure your looking at gold plated cap (silver or grey underneath or same colour. ) and not worn plated brass (bright yellow below the top layer and the chrome worn of for one reason or another). Which would probably have to be verified on site

All said there ARE gold cap variants of thes CPUs out there so a chance you may have gold cap chip board.

the gold color is a bit of an illusion... what you are seeing is the reflective nature of the doped silicon chip. unfortunately, there is nothing special about that type of chip (in terms of being gold cap). those boards should get you telecom grade.

That's what I was thinking but there's some strange fluke chips out there so I'm was going with caution.
Most of the time those are chrome nickel or plated brass if anything outside of normal; it's worth scratching in the end, just to be sure.
