The pic of the FE of this thread and a PCGS 1856 regular strike as an overlay is included below.
You will note the eagles are in a different position. When I align the eagles together, it pulls the top denticles down into the design.
Note I think the original picture for this thread is at a very slight angle, but I do not believe it would account for this much misalignment (?).
I also included pics of each with some diagnostic lines drawn and pointing
showing gaps vs. no gaps. based only on the provided picture, I don't believe these can be the same die.
Edited to add:
How to use diagnostic lines:Note there are three lines on each coin.
Find the end of each line that is aligned on a straight side of a letter (
AMERICA, UNITE
D, and STAT
ES - see pics).
See how corresponding lines in each coin start the same place, but end at a different location -- indicating different dies.
Example: On the OP's coin, look at the line running along the side of the A in
AMERICA. Note it terminates on the
I in UN
ITED.
The same line on the PCGS coin terminates on the you in United.
The other two diagnostic lines also show major differences in the layout of the OBV design.
A parallel to the beginning A (in AMERICA) has its terminus in a much different location than its corresponding line on the other coin. On the OP's coin the terminus is through the letter I on the other side. On the PCGS coin, this same line's terminus is through the you on the other side.



I know the "E line" in red looks misaligned with the letter's spine. However, I zoomed in after drawing the line and positioned it directly along the E's spine.
