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.
These ingots actually are shaped like the full sized 100 lbs industrial dore ingots the company produced and shipped back to the US for refining. The Annual Report from 1964 has a picture on pg. 4. Here is a link:
