As you found it in the US, it's unlikely to be the piece from the Australian catalogue, which suggests another company made the same pattern.
That the piece appears in the Crown Crystal catalogue doesn't mean that the ones that we find in Australia are definitely Australian in any case. They could have been made elsewhere and imported by Crown, then included in their catalogue; it could have been a copy of an overseas design; or it could have been made under licence. I'm afraid I don't know.
I can't help you with the value, I'm afraid.
