This is a very interesting toy or miniature porringer made in c1690 by maker BH ,it is in very good condition, it has the maker’s mark clearly struck twice on the base, typical 17th century form it is 25mm diameter and weighs 20 grams, it needs more research.

A really nice piece of 17th century silver
