Is this from a 400 year old money box?

To my surprise my web trawling suggests the small green glazed knob I found on the Thames foreshore topped a ceramic money box. The 'inside' shot shows  the potter's rather pleasing twist, used to create the lid.

Probably made from Surrey/Hampshire border ware. They were made between 1550- 1650, covering the life time of Shakespeare. Apparently, often found at theatres where they are thought to have functioned as box offices - could it have come from the original Globe Theatre, across the river from where I found this? 

Money Box from Museum of London 

A couple of weeks after posting this, I've just seen one of these money boxes in the Globe Theatre's exhibition,  it is so much smaller than I thought from this photograph, even though the Museum of London's photo above has the dimension. You could easily fit it into your hand.
