ALL ENGELHARD is pleased to welcome visitors to our SilverTowne L.P. Definitive Page. While our focus is clearly Engelhard, we recognize that many Engelhard bullion collectors also collect other bars and ingots. As such, we appreciate the opportunity to present important bullion information and look forward to your thoughts and input.
SilverTowne LP was founded in 1949 by Leon Hendrickson, and grew from a small coin shop to become one of the largest retail bullion and precious metals dealers in the country. What most folks don’t realize, however, is that SilverTowne produced a very limited and relatively short-lived run of poured silver ingots beginning in 1973, mostly serialized, that are just now gaining attention in the collector world.
Based on our extensive serial number database, we have conclusive evidence that SilverTowne used a single serial number run that was shared by all ingot sizes without duplication, with a total of only approximately 75,000 ingots produced nearly 50 years ago. Without doubt, a high percentage of these ingots have been melted over the years. Please note that the serial ranges below are shared between multiple sizes of ingots, so actual mintage numbers will be less than the span of the range, and to be sure, many did not survive the great melts so actual surviving examples are likely far less.
Today, SilverTowne Mint produces what we call “retro” ingots in 5oz, 10oz, and kilo weight class that in many ways resemble the vintage ingots shown below, but without serial numbers. We often field inquiries from collectors regarding these newer examples, as they often confuse them with vintage pieces. The giveaways to us are the newly poured complexion, cooling bubbles and uncharacteristic surface texture compared to vintage ingots, and the lack of a serial number. Examples can be found on the SilverTowne.com website and often on Ebay.
| EXAMPLE | OBVERSE | REVERSE | COMMENTARY | SAMPLE SERIAL NUMBERS | ESTIMATED MINTAGE | |
 |
[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.

[Inadvertent Serial Assignment] [SilverTowne Hallmark] [5 OZ.] [.999 FINE] | [Inverted Serial Number Assignment] | 1st series 5oz class ingot produced by SilverTowne. This example is an ultimate example of error bars in that the obverse hallmark was stamped over an inadvertently applied ‘13296’ serial number assignment, then struck with an inverted ‘13297’ serial number assignment on the reverse. | 13297 | 1 | |
    |
[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 [3] 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.

[SilverTowne Hallmark] [5 OZ.] [.999 FINE] | Cast Finish | 2nd series 5oz class ingot produced by SilverTowne in serial absent variation. We have been informed by a collector that perhaps 15 of these ingots were reportedly produced. To date, we have documented five examples. Please note these examples are not to be confused with SilverTowne’s current production 5oz Serial Absent ingots that are referenced in the above introductory narrative. | Serial Absent | <15 | |
 |
[SilverTowne Hallmark] [5 OZ.] [.999 FINE] | [Serial Number Assignment] | 3rd series 5oz ingot produced by SilverTowne. Demonstrates a plain reverse with serial number assignment and is the most narrow of all three series. Estimated serial run of 18000-29999 with a 4,000+ gap of unassigned serial numbers between the approiximate range of 24403 to 28405. | 18312 19718 21531 22761 23025 24264 24403 28405 28752 | <5,000 | |
  |
[SilverTowne Hallmark] [5 OZ.] [.999 FINE] | Cast Finish | 3rd series 5oz ingot produced by SilverTowne. Similar to our above example though lacks a serial number assignment. | Serial Absent | <25 | |
 
   |
[SilverTowne Hallmark] [Serial Number] [10 OZ.] [.999 FINE] | Cast Finish | 1st series 10oz class ingot produced by SilverTowne. Demonstrates a waffle pattern reverse, which varied throughout the production run. Estimated serial run of 00001-65999. Ingot 36275 in photo shows stampings on reverse of bar. This error has been noted in several examples to date.
 Our serial number database has revealed one pair of 10oz ingots with identical 04138 serial number assignment, pictured below.
