25oz Engelhard 6th Series Rare 0-Leading Early "999.0" Fineness Variety Vintage Silver Bar

Believed to be the earliest variety 25oz Engelhard due to the 999.0 purity stamp from prior to being able to refine to 999.9 fineness. This is the only Engelhard 25oz variety silver bar featuring this early fineness stamp. Only a very small handful of these 0 Leading 6th Series "999.0" Fineness are known and all are held in very strong Engelhard collections. Truly a rare opportunity to own one of these illusive ingots.
