The only thing I can say is that the cross fourchee(meaning forked) is a Heraldic symbol, I would think the date you stated would be about right, I wouldn't have said it was Crusader orientated

it seems the the Crusader cross(also known as the Jerusalem cross) was used, and exsisted for over two hundred years after the Crusade.
But I suspect you already know this

I thought the discs were coins at first inlaid, but there are no legends visible

did you find, or buy this Item......... but it's a very interesting piece thanks for showing it

If I can dig anything else up I will let you know

I have posted a picture of a Heraldic Pendant I found with a near same symbol, perhaps from the Knights Templar, like your Sword.
