Bunker Hill Company is the highest premium of this bunch. They were a notable refiner out of Idaho between early 60s and early 70s. This example is #80 which is stamped on the side outside edge of the bar. This variety has an estimated <500 examples made. Bunker Hill pieces came in 1 oz up to 100 oz size. More information can be found at allengelhard.com for history and varieties, estimated mintages, etc.
Bahamian Refining Company, interesting bread loaf style with serial/lot number stamped top center. Not much is known about them, other than they were an incorporated company in Arizona, operating in the early 1980s. I have a few interesting 1 oz pieces that I’ll post in a blog on “silver smalls.”
Buschmeyers 10 oz class. These are affiliated with the same company WGB (W.G. Buschmeyers). Very cool and highly collectible pieces. You can see my example is a 12 oz piece. They forgot to stamp the decimal. Should be 12.0. This was common with old pours. Many believe these omissions are errors, but they are not. These were hand stamped and there are many examples of slopping stampings from refiner to refiner.
Bitterroot Nugget Exchange is a rarely seen old poure out of Missoula, Montana. Montana had some great refiners, notably Chovanak, who many serious collectors covet. This BNE is a classic old pour style. I’ve come across less than 5 ever like this.
Lastly, and one of my favorite 5 oz from the “B” box is Bojuka Ryu, that was 70s era out of Marina, CA. In 1970, a small karate club was founded in Marina, CA. It grew fast and in 1974 changed its name to Bojuka Ryu. Bo stands for jujitsu, particularly Danzan Ryu Koden Kan jujitsu. Ka stands for karate arts. This one is #10 serial number. Iv’e come across one other. These are scarce and the type of pieces that make collecting ingots really fun.
