I can see two problems with identifying the name as Prentice.
First, the n is inverted. That's common enough in the C17th, but I have scanned both extracts and can't find another inverted n.
Secondly, the putative c is of a style which again is quite common, but no other example of that style can be found in either extract.
Beyond that, we have a good number of the ce letter combination for comparison, in pence and apiece. None of them look like the ce in Prentice.
I would like to see another capital P from this writer, if you can find one in the document.
