ALL ENGELHARD is pleased to welcome visitors to our Simmons Refining Company 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 additional collections and look forward to your thoughts and input!
Simmons Refining Company was located in Chicago, Illinois and earned a reputation as an accurate and trusted refiner in the 1960s and 1970’s. Their early ingots displayed an industrial looking “S” inside a crucible hallmark. These ingots were serialized and are very hard to come by today, as they were recognized as junk bars and only a few survived the great Silver Melts of 1980 and 2011. 1970’s ingots displayed the SIMMONS large “S” hallmark, and late 1970’s to early 1980’s ingots displayed the SIMMONS REFCO hallmark. While one might assume the “REFCO” designation would represent “Refining Company”, the acronym was in reality derived from Raymond Earl Friedman & Co. in New York, a financial services company specializing in commodities and futures contracts. Simmons also made many sizes of pressed bars, in weight class varying from small ‘gram’ sizes to 1oz and 10oz bars. Simmons Refining Company was absorbed by Mid-States Recycling & Refining in 1982. Our passion at AE is for vintage ingots, and it is these examples we are including on our Definitive Page.
