25oz Engelhard 6th Series Exceedingly 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 small handful of these 0 Leading 6th Series "999.0" Fineness are known and all are held as centerpieces in strong Engelhard collections. This absolutely stunning example was held in a private collection for many years and we are very excited to bring it to market. Truly a rare opportunity to own one of the most desirable vintage Engelhards known.
