Certificate of Naturalization

[califlorida]

Hi all, thanks for helping everyone out!
Question:
I'm applying jure san. through my mother. Before I knew the complexity of this process, I asked her to send me a photocopy of her Certificate of Naturalization (CoN). I have it, but will that work when I go to the consulate, or do I have to get a copy directly from USCIS/NARA?

That's all for now....I'm sure I'll have more questions later. Thanks!
