This is the only copy with father's signature, so keep it in safe place for your record.
If you need another copies of marriage certificate, you can request this when you submit marriage application form in local marriage office. Of course, you need to pay money (I remember it's about $20 per copy) for that. The copy of your marriage certificate is also the official document and recognized by other countries. It only has the signature from officer-in-charge in NV state marriage license bureau, but that's good enough.
Good luck!
