Johnson Matthey year of production.

[vw1972]

Does anybody know when this bar could have been produced?

 

The London based Company Johnson Matthey began producing silver bullion/bars in the 1980’s. The Company have now been sold to Asahi refining, and from what i can find of information online, Johnson Matthey didnt keep records of their serial numbers. 
 

And i have checked the Engelhardt webpage.

Lovely looking bar any road.

I can't add anything. This bar is shown on the All Engelhard website, with a production run estimated at under 500 bars. Once I tried to track down some SilverTowne mint serial numbers - as I remember I actually contacted them directly - no records kept. It does make you wonder what the serial numbers are about if the manufacturer isn't keeping them, it's not as though that is a difficult thing to do. One could guess the 1980's and you would probably be right.
