I make all my money clips by hand, and cut each one out myself. I do not use commercial blanks.
Each one is 1" wide, x 2" long on top.
The back is gently curved, with a lip at the end to make it easy to use. I have work hardened each one to make them stiff, with plenty of spring. This one is made from copper and has been hammered, oxidized and them polished to highlight the texture.
These clips are made to order, please allow a few days for yours to be made and shipped.
