A sign/abbreviation for "magister"

[Michael Everson via Unicode]

I think that it is the _superscription_ that indicates the fact that it is an abbreviation. 

In English “þe" was written “ye” and and “yͤ” “yᵉ” and the last of these might have a dot or a line or a squiggle underneath it, or not, and in no case was that dot or line or squiggle either _meaningful_ or necessary.
