Lot of (5) Vintage 1980 ENGELHARD 1 oz. .999+ silver bars frosted reverse PF SN
These bars are EI-1A - Landscape, frosted reverse with Serial Numbers starting with PF. Each bar is in a plastic capsule.
Produced in 1980. 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. (Info from All Engelhard)
