Twin 1956 Wheat Cents With Exact Errors On Obverse And Reverse

I collect thousands of error coins and while cataloging my Wheat Cents I noticed two different 1956 coins that have exactly the same errors on both obverse and reverse sides. The errors on the obverse are Cracked Skull errors and exhibit the exact same multiple locations where the cracks appear. The reverse side has gigantic Cuds and die break errors on the left wheat, all in the exact same locations on both coins. This would indicate to me that they were stamped on the same broken dies within very close succession to each other - possibly within minutes of each other back in 1956. What is the possibility of this? I've included photos of the obverse and reverse of both coins for your observation and comments. Do you think having these two would increase the collector value if sold as a pair? The second coin has an advanced stage of the broken die on reverse.
