I have no idea...my only guess is that I had a big bag of read heads I normally give to Mudlucky ( by big I mean BIG) but hadn't had the time to setup a drop off date with him. I suspect the platinum was in some of the surface mount components of the graphics cards. It returned off that lot and the lcd logic boards. I depoped ta caps and mlccs off of...half or more of the stuff I came across. I had bags and bags of bluetooth chips that failed QC at a local e-waste pickup, platinum returned from that too. Eaton corp had solid state drive controllers (kind of bulky) that also failed QC so I had some high density flatback boards and some RFID stuff too. Yanno...it's really difficult for me to finger where the platinum came from... I also had a pile of business phone corded and cordless boards...a big pile I won an auction of about 200 of these.
Way I figure it...these are things I wouldn't get from a standard gold return anyways. The silver was a seriously heavy amount that impressed me and made me realize in some cases the silver is a higher return than gold...as it happens.
