I don't understand your request

Can you link entries or mint pages in which you see errors?

From the viewpoint of our underlying documentation, we have this:

The mint mark, the angel head, is derived from the city patron, the Archangel Michael, and was used between 1612-1794. The letter B was sometimes used before 1612 and between 1821-1830. In the 20th century, the cherub's head was again introduced as a mintmark

I searched on the term “barbell” under Begium and did not get any matches.

So, I agree,  I do not yet see anything to act upon here?
