In my opininion the nails you use are not as critical as how they are installed.
Make sure to take the time to use a punch or small hammer and set the heads BELOW the surface of the plastic or rubber. Ive had good luck using oversized nails when the holes are reamed out by taking linemans pliers and snipping off some of the length and then nailing them in properly.
obviously less options with some coin-op pocket types
Good Luck,
