Vintage Anson Black Hills Gold Cufflinks
I bought these as Anson. They have an A stamped on the back. They are Black Hills Gold with three colour gold leaf design on the front. They call the colours yellow, green and pink. I think it is just the design that is 14k gold with the rest of the cufflinks being gold coloured metal. Check out wikipedia for more info. I cannot guarantee that the gold content, I am not a precious metal expert.
Excellent vintage condition.
