This page contains our current information on 100oz class Engelhard silver production bars and Legacy Ingots.  
For substantial bullion investors looking to accumulate quantity and quality bullion, there is no better match than the 100oz Engelhard commercial bar.  These iconic bars are immediately recognizable in the bullion world as ‘the standard’ of value and exchange.  While approximately 800,000 examples of all US and Canadian varieties were manufactured over Engelhard’s tenure, a very high percentage of these bars were melted over the years for industry and smaller increment fabrication to bars, rounds and jewelry.

One of our regular contributors reminisced about a day, in 2010, when he walked in to a prominent Daytona Beach jewelry store and noticed half an Engelhard 100oz 1st series bar on the counter.  He jokingly asked, ‘where’s the other half?’ and the salesperson replied, ‘we only use Engelhard silver to make our jewelry and rounds.  It’s the most trusted silver.’  This particular merchant designs and fabricates between 15,000 to 20,000 1oz custom silver commemorative rounds every year for ‘Bike Week’, and they have been doing this for some 25 years.  Hence, their production consumes 150-200 Engelhard 100oz bars every year for these custom rounds.  Makes you wonder if there are other similar stories out there!

All Engelhard is grateful to have sourced this variety’s history from the original owner of bar A0006.  This 100oz Manfra, Tordella & Brooks bar was produced by Engelhard in the 1970’s for MTB Bank, New York.  It is speculated these bars were offered to customers who opened a new account at MTB Bank, New York, with $100,000.00 deposit and that only ten of them were produced.  This ‘A’ prefix serial range is shared with MTB bars in 5oz and 10oz class.  Bar A0454 sold privately on January 20, 2017 for $4,000.00.  Additional information regarding the MTB counterstamp may be found at this LINK.  A0006

  • The 6-digit landscape variety without letter serial prefix that include three-trailing zeroes on weight designation were the first produced.
  • The 6-digit and 7-digit landscape variety in ‘T. OZ’ designation came second.
  • The 5-digit landscape variety in three-trailing zero weight designation came next, to include ‘MFR’ variation.
  • The letter-prefix serial number landscape examples with the Standard Engelhard Logo came next, to include both poured and extruded production.  These include ‘P’ prefix, ‘S’ prefix, ‘W’ prefix and ‘C’ prefix serial number designations.  We believe there was some assignment overlap during production, in that serial number prefix is not necessarily indicative of variety production order.
  • The  Engelhard ‘Italic Block Hallmark w/ ‘A’ Triangle’ landscape variety was the last to be produced.  We believe the ‘MTB’ portrait variety was produced shortly prior to the end of of the ‘Italic Block Hallmark’ examples.
  • There are three known counterstamp variations, including Manfra, Tordella & Brooks, SilverTowne and Gold Standard Corporation, that were contract produced.
  • There are unsubstantiated claims that ‘P’ represents ‘poured’ and ‘C’ represents ‘cast’ in serial prefix. We challenge this theory, as it was the casting method by which Engelhard produced their poured ingots. Casting is quite similar to making ice cubes in a freezer, in that liquid [molten metal] is used to create a solid ingot by use of a mould. As such, the terms ‘poured’ and ‘cast’ are synonymous. Further, Engelhard could not have designated a ‘P’ prefix in anticipation of the ‘C’ prefix series as advancement of their production technology was likely not foreseeable when they designated the ‘P’ prefix. There are also claims that ‘W’ represents ‘wide’ series, which is doubtful because the majority of 10oz pieces were produced in wide [landscape] variety. We speculate, at this time, that ‘W’ is representative of the Engelhard ‘West’ Facility at which they were produced and that ‘P’ and ‘C’ were likely arbitrarily designated.
  • NOTE:  There may be duplicate serial numbers, not of the same design, due to the Triangle Logo variety ‘rolling over’ after hitting P999999.
