You didn't show us in that screenshot what happens with the following commands:

Code:

x=abc$123
echo "$x"

You said you got:
abc
I said that instead, it should have produced:
abcsome(possibly empty)string23
where some(possibly empty)string should be the same thing you get from:
printf '%s\n' "$1"
