AUTOGRAPHS

In ASL how do you sign upper case letters?

How do you sign versus lower case letters
Americal Sign Language
Say you are signing a password with letters and numbers which have some uppercase ones (such as bY94Th)

It depends on the context. Generally, it’s not necessary. What is the sentence?

EDIT: Basically, you’d say “Big” or “small” before you sign the letter. Do it for all of the letters though, not just the capital ones.
