Need help with silver hallmarks

Hi all,
I have 3 medieval silver cops. They all have same hallmarks later crowned later A and 3 towers. Can some body tell me what period this hallmarks form.
Thank you, Glenn

Hi, this may not be much help but the three towers could be a Danish mark.

It is not Danish - period, no chance what so ever.
3 crowns is Sweden - but this is not the swedish mark either.

The crowned A - is 2 marks. An A and a mark of a Crown - cannot find any match.
To the best of my knowledge I would sugges Hanau pseudomarks. But it is a guess.

Should I suggest something else - have you considered Newcastle?

but Hanau is my favorite. Also age - Hanau produced copy of these very old things. Chance of finding 3 matching cups from that time ???
