Sporrong gold

[Figleaf]

I am taking this for an advertising medal on the strength of the slogan INVESTERA I GULD, although that is not Sporrongs business. I think the key is the mention of Norrtälje, a place in Sweden where Sporrong moved its production facilities in 1964. In 1984, these facilities were re-located in Ekenäs in Finland. Sporrong has been owned since July 2018 by Kultakeskus OY, Finland's leading metal processing company based in Hämeenlinna. This company does trade in gold. It is possible that Sporrong's head office in Stockholm acted as agent for Kultakeskus OY before the takeover.

The portrait on the other side may refer to a Swedish gold coin.
