To make a Peso sign in Microsoft Word, first put the cursor where you want to insert the sign, and click the "Insert" tab.
On the far right side is a drop-down menu for symbols. From the menu, select "More Symbols." This will open a pop-up that lists all of the available symbols in Word.
There is another drop-down menu labeled "Subsets." On this menu, scroll down about halfway through the list until you reach "Currency Symbols." On the second row (or thereabout), you should find the Peso sign. Select it and hit the insert button located at the bottom of the box. (Hover your mouse over each symbol for a pop-up information box.)
