Yardney Electric Corporation was founded in 1944 in New York City. They were among the first companies in the world to successfully produce and commercialize rechargeable silver-zinc and magnesium silver chloride batteries. They were acquired in 1969 by Whittaker Corporation. In 1970, the company moved to Pawcatuck, Connecticut. They went through a series of changes over the years and today are known as Yardney Technical Products. Many of the ingots they did were presentation pieces and have initials of the recipient stamped on the ingot. I have two serializes pieces that are not personalized. I believe these to be much less common and very happy to have them. Each of these weigh 4 troy oz. This is common for all Yardney pieces.
