ALL ENGELHARD is pleased to welcome visitors to our Harringtons Metallurgist Pty Definitive Page. While our focus is clearly Engelhard, we recognize that many Engelhard bullion collectors also collect other bars and ingots. As such, we appreciate the opportunity to present important bullion information and look forward to your thoughts and input!
In the early 1980’s up through the mid-1990’s, Harringtons was a significant Australian mining and bullion player in its day, with LMBA accreditation along with the likes of The Perth Mint and Johnson Matthey, although the ingots shown below preceded their LMBA designation and evolved when Harringtons was very young in its history. These ingots, represented in all the common sizes of the larger refiners as well as odd weight ingots, are quickly garnering attention from collectors around the world for their crude beauty, very limited and mostly serialized production of less than 10,000 total ingots, and outright scarcity in today’s market.
