I have a few more very rare and unique pieces from Rosario Mining to share today. I shared a 4 oz example in my “Notable R Hallmarks” post some time back. Rosario mined the Mochito Mine in Honduras (the H in the NYH stamp). Most of their rectangular shaped ingots were presentation pieces to shareholders, but these below, I believe were done in very limited capacity, perhaps for employees, but hard to say for sure. Enjoy the pics.

There are several other “R” ingots that I’d like to highlight for fellow collectors. First up is a bar that was incorrectly labeled as Rainier for quite some time. We have discovered provenance that this is in fact Rainbow Vacuum, which is a product of Rexair (still in business today). It only came in 15 oz and we believe was given to customers and or internal employees as gifts and or rewards.

Next up is Rio Grande, which looks almost identical to the mold that Academy used for their “finger pour” bars. Rio Grande also did 1 oz commercial art bars. This is the only pour variety I have come across for them.

Rosario Mining is last up. These are really cool pieces. The company was based in New York with mine in Honduras. Note the NYH stamp and you will know the meaning behind it. These were presentation pieces given out to shareholders of the company. They did come in several varieties.

I decided to pair these two old hallmarks together, as they are cousins. If you look at the 5 and 10 oz mold on these, you will notice they fall into the what we call the Doyle’s Mold type. It has always been believed that many of these bars originated around Southern California, as this is where Doyle’s Mint was located. We recently got some provenance that proves Regold indeed was in Southern California. In fact, it was founded by John Rego, who was also the founder of JJSR. Regold was later mentioned in advertisements as formerly being J & J Smelting and Refining, which is really an amazing find in terms of the history. See the below pic with the back story.

Riverside Coin & Gold was in Riverside, CA, but not a lot of info available on them. RCG is the stamp within the state of CA hallmark. These are highly collectible and have become harder and harder to find.

RMMR old pours are thought to be the same company as RMM out of Salt Lake City, Utah, known for their extruded bars (same style as the Swiss of America and Kingsmen bars). These old RMMR pours are very well done and have tons of character. Here are a few examples for your viewing pleasure.

Here are a few killer examples from Brian R’s collection, which includes a very scarce 5 oz example.

This hallmark is a favorite of mine and among the more recognized hallmarks from the “R” box. The company operated in the early 1980s out of Anaheim, CA. They poured bars primarily in 5 and 10 oz class, but also did 1 oz silver rounds and bars, including rounds specifically made for Disney. Premiums are high on the bars if you can find them. Many have a double stamping phenomenon common for this maker.

Here is another fantastic 5 oz example from Brian R’s collection.
