This page contains our current information on 20oz and 25oz class Engelhard silver production bars and Legacy Ingots. The 20oz Engelhard ingot is considered by many collectors as one of Engelhard’s most appealing pieces, as its large flat surface area beautifully displays the various stampings and hallmarks, while the relative thinness of these ingots accentuates the cooling lines in production creating beautiful and unique toning and patina. We believe total 20oz production to be less than 15,000 ingots, and without doubt many were melted over the years. Note that many 20oz varieties are Tier 1 and Tier 2 classified ingots.
Please see our 20oz and 25oz Counterfeit Registry pages for additional information.
The 25oz Engelhard ingots are uncommon and all varieties are considered very rare and desirable for collectors. We estimate total mintage of all 25oz varieties to be less than 3,000 ingots, many of which were also melted over the years. All 25oz examples are Tier 1 classified with exception of the 1st series example, a highly desirable Tier 2 ingot.
