|[SilverTowne Hallmark] [5 OZ.] [.999 FINE]||[Serial Number Assignment]||1st series 5oz class ingot produced by SilverTowne. Ingots of early serial number assignment demonstrate a plain reverse while ingot 10068 demonstrates a lined reverse. The serial number assignments for these 1st series ingots were random throughout the range. This 1st series ingot measures approximately 52.39mm x 19.05mm. Size differences between all three series are demonstrated in the photo below, with 1st series being decidedly more wide than the others.||00050|
|[SilverTowne Hallmark] [5 OZ.] [.999 FINE]||[Serial Number Assignment]||2nd series 5oz class ingot produced by SilverTowne. These ingots were produced in both lined-reverse and flat-reverse throughout the serial number range, both pictured. This 2nd series ingot measures slightly narrower than the 1st series, at approximately 49.21mm x 19.05mm. SilverTowne used many slightly different casting moulds and cooling trays in their production of these ingots. In an All Engelhard case study of 100 2nd series ingots, we found 30 examples with inverted serial numbers of random serial range assignment. This suggests the inverted serial assignment was perhaps a production oversight, though not terribly uncommon. Mintage estimate on these inverted serial number examples is <2,250 of the total <7,500 produced.|
It is rumored that three  5oz class ingots were erroneously stamped with serial number on the obverse, while the hallmark, weight class and purity stamps were placed on the reverse. This is demonstrated in the photo of ingot 00052, below. Ingot 04813 has also been documented to show this reverse stamping anomaly. It is also rumored that a few 10oz class ingots were stamped in similar variation, though we have not yet observed such an example.
