One engineer admitted it to me in a personal conversation, but I would rather not mention names here. It is legal in some countries and legal below some limit even where prohibited at high concetrations such as would be used by Kodak.
They use DDT in some countries.
For those who are still interested in prices, Strem Chemical will sell 25 g for $480, or roughly $20/g, or 5 g for $140, which is $28/g. On the other hand, it's > 99.9% purity.

Reason: Second price quote came in late
I suppose a few are using it to brew Nelson's Gold Toner.

Nelson's is essentially a hypo-alum sulfide toner where the
minute amount of gold present modifies the color from
sepias to warm blacks. Also, I suspect the gold acts
as a catalyst as Nelson's will tone even at room
All that is from reading. I've all the ingredients and hope to
be working with it by winter. Dan
there are a whole slew of gold toners, GP-1 is very popular, as well as the Nelson's gold mentioned in the above reply.
Then there is Blue-gold toner, or a whole list of other formulas available
Just as an FYI, the Nelson's gold does better warm and will split as well. Be sure to use a fixer with hardner after toning

Actually I don't think Nelson's should be considered a Gold

Save for some Hypo-Alum toner, I think Nelson's may be
the least costly of all archival toners. Dan
So the best source I found was mostlymetals.com. It's run by an alt-process printer who sells as "nukey235" on eBay, and it started as a buyers club so people could make group orders in quantity, but he said that it was difficult to coordinate the groups, so he started just making the large orders himself and selling it, at what I'm guessing is a pretty low markup, given his prices. I won 3 g for $60 on eBay and asked if he had more at that price, and said he would sell it at an even lower price, depending on quantity. So I purchased 25 g at $17.40/g last week (and the price is going up), and it arrived today. I haven't toned with it yet, but it indeed looks like 25g of gold chloride and not, say, orange sugar crystals.
He also sells precious metal salts for pt/pd and other processes.
Goodness how times have changed!! ^^^ $13 in 2003 adjusted for inflation for 2013 is really about $17 and the least I can find gold chloride is $45 a gram at Artcraft.com

WOW! I hope you have a insurance policy for that kind of scratch! I've never thought about insuring my dr chems, but you're sitting on $6K+ of liquid! That's like a ultra rare bottle of Dom Perignon sitting in a mere brown bottle or whatnot! haaaa
500ML of 5% = $1000!!!
