CONSOLIDATED MINES & METALS

 ENGELHARD
 
is pleased to welcome visitors to our Consolidated Mines & Metals 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!

Consolidated Mines & Metals was incorporated in the State of California on March 26, 1975 and operated out of San Fransisco, California.  The most notable differences in the production of Consolidated Mines & Metals, in relationship to other ingots, is the incredible attention to pour properties, superior mirror finish quality and hand craftsmanship in every bar.  These bars are highly prized by investors and collectors alike.  A higher premium is established when a collector is able to obtain the original Consolidated Mines & Metals certificate of fineness.  

Please note the serial numbers presented below are an exhaustive list sourced from our archives.  As such, collectors are encouraged to provide us any additional numbers they have as we continue to fine tune our mintage estimates.
