AG | 1oz

This page contains our current information on 1oz Engelhard silver bars and Legacy Ingots.  Engelhard 1oz bars are, in general, the most common and available of all Engelhard sizes produced.  With total production at a relatively limited 4 million units, 1oz Engelhard bars are the ideal choice for investors looking to secure desirable hallmark bullion as well as a collectible piece of Engelhard history. 

While 4 million units over a span of two decades may seem like healthy production, it is important to note the ‘ultra rare’ 1996 US Silver Eagle had a production run of just over 3.6 million rounds in its most limited production year, currently commanding upward of 3x spot price. Unlike the 1996 US Silver Eagle, a meaningful percentage of these 1oz Engelhard bars were melted during the 1979/1980 silver spike.  When comparing the relatively short 4,000,000+/- 1oz Engelhard bar run with the continuously increasing 525,000,000+ to-date production US Silver Eagles, it is easy to recognize why many bullion investors and collectors continue to invest in these 1oz Engelhard bars.  Imagine, more US Silver Eagles are produced in a single month than the entire Engelhard 1 oz bar production ever.  If that isn’t a compelling argument to pursue every last 1oz Engelhard bar on the planet at today’s prices, we don’t know what is! 

Presented below, we define all currently known varieties with pictures, serial numbers and mintage estimates.  There are surely a few more we haven’t encountered yet, and we welcome collectors to share any new discoveries.  We hope you enjoy your visit!

	N/A	N/A	[1.000]  [999+]  [Hallmark in Elongated Octagon]  [Serial Number]	Blank, without a border.	Produced in the late 1960’s, this is the earliest known variety of 1oz Engelhard production bar.  The examples we’ve observed demonstrate a faint ‘X8’ over-stamp to the left of serial number.  The serial number errors on these pieces resulted from part of the letter ‘X’ and number ‘8’ that were used as fillers for the lead position on the rotary stamp.  These leading fillers slipped out of position just enough to leave an impression of the bottom or top half of the letter and number, see our recent article ‘THE X8 FACTOR‘ for additional information.  Bar 10038 sold privately on August 12, 2016 for $2,500.00.  Bar 10088 sold privately on July 28, 2017 for $2,750.00.  Bar 10023 sold via eBay auction on May 2, 2021 for $2,555.99.  Additional information regarding this bar may be found at this LINK.	10023 10030 10031 10038 10062 10063 10088	<100 MINTAGE

Believed to have been produced from 1975 to 1980.  Note that the Engelhard logo is slightly different than on other varieties.  The left and right sides of the rectangle are longer, and this appears to be the first Engelhard logo, and the ‘H’ and ‘A’ are noticeably wider.  Note this variety has the ‘1’ in weight designation centered above the space between ‘.999′ and ‘FINE SILVER’.	N/A	<25,000 MINTAGE
	EI-1A	Art Bar | Frosted Reverse | Serial Absent	[Hallmark in Elongated Octagon]  [1 TROY OZ.]  [.999 FINE SILVER]	Blank, with a border.	Believed to have been produced from 1975 to 1980, similar to our above example though demonstrates a pebbled finish on the reverse.	N/A	<10,000 MINTAGE
	EI-1AV2	Art Bar | Frosted Reverse | Serial Absent	[Hallmark in Elongated Octagon]  [1 TROY OZ.]  [.999 FINE SILVER]	Frosted, with a border.	Believed to have been produced from 1975 to 1980.  Some of these have the original logo, as pictured here.  Others have the revised logo with the shorter left/right sides and more space between the letters.  The example pictured demonstrates a coarse frosted reverse and not typically observed with engraving.  At least some examples were issued in a maroon plastic pouch and presentation box, commonly reserved for Engelhard gold bars, pictured below.

	EI-01AV EI 1AV	Engelhard Commercial Bar	[Hallmark in Elongated Octagon]  [1 TROY OZ.]  [.999 FINE SILVER]  [Serial Number]	Frosted, with a border.	The purity stamp was revised from ‘.999 FINE SILVER’ to ‘.999+FINE SILVER’ and  font changes were made [e.g. the ‘S’ in ‘Silver’ was changed from a serif font to sans-serif] and the ‘H’ in Engelhard is slightly wider. Apparently, few survived melting. Note that some have a single letter prefix [‘P’] and some have a space between the prefix and the numbers [e.g. ‘P   59250′].  Occasionally observed in serial placement error as seen on bar PA83079, also pictured.

FINE SILVER .999+]  [Hallmark in Elongated Octagon]  [Serial Number]	Hallmark in Elongated Octagon repeated diagonally, three full times, with a border.	Believed to have been produced in 1981.  From the numbering, it appears that the ‘F’ serial numbers started after running out of the ‘P’ numbers.  The series appears to have ceased production in the middle of the ‘FB’ serial numbers.

	N/A	Engelhard Commercial Bar | MC Absent	[Wide ‘E’ Centered in Globe Logo]  [1 TROY OZ.FINE SILVER.999+]  [Hallmark in Elongated Octagon]  [Serial Number]	Hallmark in Elongated Octagon repeated diagonally, three full times, with a border.	This variety lacks the two-letter prefix as seen on the entry above, and has a 6 digit serial number that we believe corresponds to the Canadian run shared with 1 oz Maples and larger sized ingots.  The mould size of this bar is uniquely larger than the Wide ‘E’ above.  This variety has a dot in the center of the bull logo. Note the erratic number 7 in the bar pictured that indicates this was hand stamped.	261774 262217 262898 263412	<100 MINTAGE

FINE SILVER .999+]  [Hallmark in Elongated Octagon]  [Serial Number]	Hallmark in Elongated Octagon repeated diagonally, three full times, with a border.	Similar to above EI-9 variety but in attractive proof-like finish with frosted detail.  This new variety was discovered in 2014, when four bars, each encased as a paperweight, were offered for auction.  We have authenticated these unique U.S. serial prefix examples and confirmed that shape and weight of the encasements match those of other 1oz Engelhard promotional paperweights. Note the unique U.S. letter prefix is the only 1oz variety to demonstrate a period after each letter.	U.S. 0110 U.S.  0372 U.S.  0310 U.S. 0412 U.S. 0491 U.S. 0530 U.S. 0657	<500 MINTAGE

Produced in 1981.  Same as our above example, but in serial absent variation.	N/A	<2,000 MINTAGE
	EI-09V EI-9V	Engelhard Commercial Bar | MC Absent	[Large ‘E’ in Globe Logo]   [1 TROY OZ FINE SILVER 999+]  [Hallmark in Elongated Octagon]  [Serial Number]	Hallmark in Elongated Octagon repeated diagonally, three full times, with a border.	Produced from 1981-1985.  We believe there are three possible varieties to include a smooth ‘E’, a frosted ‘E’ and a third variety with a roughly frosted ‘E’ some of which demonstrate a proof-like finish.  Many FN and PR serial prefix examples demonstrate reverse variations of top right and bottom left hallmark border placement. Thanks to GOOB for these observations!  We believe the most rare and highest premium examples include the proof-like finish with frosted logo and reverse stamping variation.  One collector noted he purchased several FL prefix bars in plastic wrapper from Cypress Bank in Tampa, Florida, circa 1981.  Occasionally observed in serial placement error as seen on bar FJ67468, also pictured.

Design appears to be exactly the same as the EI-9V, above, except in a 6-digit serial number variation without letter prefix and lacks the center dot in the Bull Logo.  Also, the edges do not have a very tall border, making it more likely they will be worn prematurely from handling.	276507 278681 380292	<2,000 MINTAGE

Produced in 1981 and very similar to previous variety, above.  The reverse is blank without border and the obverse was changed slightly [1 TROY OUNCE] was centered and the Maple Leaf Logo was redesigned on some examples.  Interestingly, the design may have reverted back to the original at some point, as one collector showed us a picture of the original variety with a serial of 357522.  Our serial number registry suggests this serial assignment was shared with other variety and not indicative of full range.	030316 058604	<5,000 MINTAGE

• Most Engelhard 1-ounce silver bars have serial numbers (two do not, but are otherwise identical to other bars). The bars without serial numbers should be considered art bars.
• Most have serial numbers beginning with 2 letters (the first being ‘F’ or ‘P’). The exceptions that 2 varieties that are just numbers, and bars with a ‘P’ with no other letter.
• Most have serial numbers ending in 5 numbers. The exceptions are some that have no letter prefixes, and ‘PB’ (which have 6 digits)
• In most cases, it seems that when the numbers reach ‘99999’, the 2nd letter is increased (e.g. after FA99999 is created, FB00000 or FB00001 is created).
• There is at least one case where two designs appear to share the same prefix (FB seems to be shared by two designs)
• There is at least one case where one design has serial numbers beginning with both ‘F’ and ‘P’ (the ‘Wide ‘E’ centered, with FA, FB, PX, and PZ).
• We count about 45 different prefixes as well as the no-prefix 5 digit.
