First sale
This was refined from server midplanes made around 2002-2004.
I still have more of the connectors from the same batch sitting in AP, as well as other batches for different pins, and gold fingers / gold plated PCBs.
They were sold to a local refinery in Belgium.
Since I was curious about how much aqua regia followed by SMB would improve the purity, I decided to do 2 beads with AR, and for the 2 last ones, I simply melted the foils I got after Acid Peroxide.
The refinery did an xrf test on each bead, unfortunately, they forgot to print the report, so its only hand written on the sales receipt, but I'll make sure to get my report next time, for my records.
Purity was 994 and 991 for the 2 beads made after one step of AR.
And I was very surprised to get 986 and 984 for the two beads that were melted straight after Acid Peroxide without any further refining.
They offered 90% of spot (and adjusted for my purity), that's the same price they would offer for stamped jewelry or "old" coins.
I will probably still try one bead with 2 steps AR to see how pure I can get my gold, but I won't bother doing AR on anything else I'm going to sell immediatly.
This is an extra step that won't make any difference when reselling to them.
I will still probably do at least one AR step for the gold I will stack, just because I can.
Now, I need to find a cheap way to "hot stamp" some custom tokens for the gold I'd like to stack.
