Another recognized CA hallmark, the SD bars have a great look and have developed a strong collector following as the vintage ingot hobby has grown. The company started in 1979 out of Escondido, CA (not far from San Diego). They primarily produced 5, 10 and 20+ oz bars in different varieties, some with the characteristic picture frame style and some without. Very cool pieces. The company is still in business and can be visited at http://www.sandiegorefining.com.
Is the picture frame one older or more recent?
Hi Steve, the 5 oz picture frame would be the most modern of the 3 pictured, the non picture frame 10 oz is the oldest here.
