Thanks.
I did see on one thread (or other) that the “d” meaning pence or cents or whatever it is on the Kenyan doc could have been a “c” with a line through it vertically?
I have no freaking idea.
The cent sign that is no longer on the keyboard started out as a “c” with a vertical line through it. When penned it look more like a d.
If you are into construction the penny nail uses a d for penny. (d10 is a ten penny nail.) Penny = Cent.
You might be able to find more information on it somewhere on line.ALso interesting is the evoluction of p and f .......PH as in PHish.
