I requested a copy of my birth cetificate and marriage certificate when I enlisted. I was given small wallet sized copies of both. I asked the clerk if those were going to work and she said that what mattered were the embossed seal, certificate numbers and signatures. Any one of those things missing voided it. She said I could take in a piece of wood with all of the pertinent info on it and if it had the seal, certificate number and signatures, it would be accepted.
