Undated (1964-1968) United States Assay Office at San Francisco "Grease Bar" Silver Ingot. 100.09 Ounces.200 mm x 88 mm x 18 mm. The only "marking" is in the upper left quadrant of the front face, where the weight 100.09 has been applied in grease pencil. There are no other markings, hallmarks, etc. on any face. All faces except for the back are moderately toned in antique pinkish-silver and steel-russet, the back essentially untoned apart from an irregular splash of reddish-russet in the center. We note only the expected imperfections from the mold, and no significant post-production blemishes save for a few tiny reeding marks over the lower right quadrant on the front that suggest this piece was stored with coins for at least some period of time.
