Even with the raised seals they can be copied. Long ago, I worked in a bank when all there was were the raised seals. When we had to copy an original, we would color the seal by rubbing the side of a pencil lead over the seal so it could be seen on the copy.
When my Mother was in rehab they wanted to see the original. So I made several copies and left the copies at home. They made a copy of original and than gave original back. Never NEVER give up original. I think if has to do with the raised seal.
Yes make sure you keep originals in a fireproof locked box. By the way, our originals which are done by an expensive lawyer, do not have any raised "seal". They have ooriginal signature of my mom or dad, 2 witnesses, and the notarization stamp A raised seal might be used by some notaries but not all and does not mean its more official, its just different (and they use thicker paper).
