This page contains our current information on all known varieties of Kilo and 1/2 Kilo class Engelhard Legacy Ingots. Yes, all varieties displayed below are considered ‘uncommon’ or ‘rare’ and regarded as highly desirable and collectible ingots. The ½ Kilo class includes 500g, 0.5kg, 16.075oz and ½ Kilo weight class designations. The Kilo class includes 32.150oz, 1kg and 1 Kilo weight class designations.
ENGELHARD LONDON Kilos and 1/2 Kilos were produced in Portrait (tall) and Landscape (horizontal) varieties with numerous alphabetic prefixes throughout the production span, which we believe to be from 1960 to 1973. Based on our extensive serial number registry, we estimate that approximately 15,000 silver Engelhard London Kilo and 1/2 Kilo ingots were produced over 15 years, averaging 1,000 pieces per year. As these were the ‘most trusted bullion’ ingot available at the time, most were melted for other fabrication like jewelry, photography, medical equipment, etc. Over 16 years, we have logged only approximately 4.00% of the 15,000+/- Engelhard London Kilo and 1/2 Kilo ingots produced, suggesting (based on similar ingot studies for same era and mintages) that perhaps less than 20% of Engelhard London Kilos have survived repurposing and the great melts. Below we have outlined Engelhard’s London Kilo and 1/2 Kilo production, in order of alphabetic prefix. Engelhard used a single serial number run encompassing all prefixes, with many sizable gaps that were likely reserved for Engelhard London gold ingots, but many of these serial voids were never filled.
The Engelhard London hallmark ingots shown in Kilo and 1/2 Kilo weight class are highly coveted Legacy ingots and of the earliest Engelhard variety. They are all in high demand and at the top of the collectibility and rarity list.
Additional information on these varieties can be found within our ORIGINAL PUBLICATIONS archives. We hope you enjoy your visit!
