Undated San Francisco Mint Strip Cast / Sheared Silver Ingot. Type II Oval Hallmark / Full Type III Oval Hallmark. No. 907. 26.35 Ounces. 999.75 Fine. 73 mm x 99.5 mm x 12 mm (greatest dimensions). An extraordinary example of this impressive San Francisco Mint ingot type. The front face is stamped (Type II oval hallmark) / 907 / 26.35 OZS.. / 999.75 FINE, while the rear face has a full, large Type III oval hallmark measuring approximately 56 mm x 36 mm. Bright silver-gray surfaces show no post-production blemishes of note, just the usual casting imperfections and other as-made features.<p>According to Ken Conaway, author of the website <em>silveringots.com</em>, "Every example [of this ingot type] Ive examined in hand or studied in photograph, has one or more sides evident of having been cut with a metal plate cutting sheer." The present example has been cut along the left edge. It is particularly notable for having a full Type III oval hallmark on the rear face, as above, since, again according to Conaway, "most of these Type III Oval Hallmark reverse stampings fell victim to a cut." As of this writing, the author lists 57 examples of the strip cast / sheared type in his registry of silver ingots from the San Francisco Mint. All of the dated examples therein are from the 1950s. The present undated example is not included in the Conaway registry. It is a rare and exciting specimen that represents a significant find for the specialist.
