Anyone ever concidered having a multi-element assay done on some of these gold plated
puter pins?
Or, perhaps Chriss knows what could be there?

There are so many different makers so a specific analyze on one pin would not tell a lot as you wouldn't know the maker or model.
The easiest way is to read the data sheets of components for sale. After reading a couple I see a trend.
1. Molex pin
Base material : Phosphor bronze
Plating alternatives : 30 u" Au, 15 u" Au, Sn
2. FCI pin
Base material : Phosphor bronze
Plating alternatives : 0.76 um Au, 0.36 um Au, Sn
3. 3M receptacle
Base material : copper alloy
Plating : 100 u" Ni with 12 u" Au
4. FCI card connector receptacle
Base material : brass, spring BeCu
Body plating : 30 u" Au over 50 u" Ni
Spring plating : Gold flash
5. Molex board connector
Base material : Phosphor bronze
Plating: 1.00 microns Tin/Lead /2.00 microns Copper min. (.000040" Tin/Lead /.000080" Copper min.) or
0.50 microns Gold/0.75 microns Nickel min. (.000020" Gold/.000030" Nickel min.)
6. Another molex pin ...
0.38 or 0.76 um Au over Ni and phosphor bronze.
This was only a few of the 26000 different products under connectors - PC-board. The picture is quite clear, there exists four standard platings, tin, gold flash, 15 u" and 30 u" on nickel. Body material is phosphor bronze or beryllium copper in springs.
I hope this helps.
