This page contains our current information on 10oz class Engelhard silver production bars and Legacy Ingots. For many collectors and investors, the 10oz Engelhard bar represents the standard and preferred bullion choice. Engelhard 10oz bars are a comfortable size to handle and serve as an ideal store of value for investment and trade.As with the smaller weight class Legacy Ingots, Engelhard 10oz ingot lineage witnessed many variations through early production years.
These variations include placement of hallmark, weight and purity stamping as well as frequently erratic and crude serial stamping. Amazingly, these ingots were generally considered junk bars and frequently melted until just a decade ago, when collectors began to appreciate their inherent beauty and undeniable scarcity. Engelhard 10oz Legacy Ingots are now among the most sought after on the collector front.The most well-recognized of the 10oz bars are the ‘P’ prefix 7th and 10th series poured bars, produced at the Plainville, Massachusetts plant in the late 1970’s. These examples were designated ‘P’ prefix to represent the Plainville, Massachusetts facility, while examples designated ‘C’ prefix represent the Cartaret, New Jersey facility.
10 oz Engelhard Cast Silver Bar.999 Fine (7th Series) Please note the back of the bar may have a smooth or waffle finish. Engelhard silver bars are vintage products that are no longer in production, and their cast bars are very popular with collectors and investors because of the rich history associated with the brand and the quality of its products.
These bars, along with the later 11th series pressed bars, have been regarded as the benchmark of Engelhard investment grade bars. With total production of approximately 100,000 ingots combined for 7th and 10th series, and 200,000 +/- for 11th series, they were relatively common in their day. However, many have been melted over the years, further fueling the collector market’s high demand for these iconic bullion examples. The 12th series ‘P’ and ‘C’ struck commercial bars are also gaining enthusiasm in the collector world, as the availability of earlier series bars continues to quickly diminish.Portrait Varieties: EXAMPLEHALLMARKOBVERSEREVERSECOMMENTARYSAMPLE SERIAL NUMBERSICR ESTIMATED MINTAGELarge ‘E’ Hallmark MC Absent.

Many studied examples across serial number range demonstrate small variations of font die and casting shape. We believe the wider spacing on weight and purity stampings began around 75xxx.
Despite the seemingly wide serial number range, we believe these 5-digit ingots were only produced randomly in small runs and are, in fact, quite rare. Custom ‘UNITED’ Hallmark 10.000 999+ Serial NumberCast Finish3rd series in 5-digit serial, United Refining counterstamp variation.

Additional information may be found at this.07792. 3rd series in 6-digit serial variation with a number ‘8’ leading prefix. This variety demonstrates a ‘^’ over-stamp to the left of serial number. The serial number errors on these pieces resulted from part of the letter ‘X’ that was used as a filler for the lead position on the rotary stamp. This leading filler ‘X’ slipped out of position just enough to leave an impression of the bottom or top half of the letter. The bottom picture, bar 11948, demonstrates the bottom half of the same ‘8’ that was stamped on previous pieces had slipped back into the same position as the leading ‘X’ number to its left.
Also note the strength of the impression left by leading number ‘8’ due to its lack of use. We have registry entries noted for these error pieces in very tight ranges between 811855 to ‘8’14487 to include the unique ‘Y’ prefix variety such as ‘Y’12590 and believe that this range was shared with the 100oz examples with zero prefix.

Analysis indicates these were produced in specific serial runs of 36xxx, 59xxx and 65xxx and have estimated mintage accordingly of 50-100 examples on each run. It is important to note that ‘MFR’ is not a serial number suffix as some collectors may claim.
The 100oz class examples confirm this as their serial number and ‘MFR’ designation are stamped on opposed corners of the ingot.
