Maybe its been discussed or theorized but i think the coin puzzle is the lore for Angela.

In order on normal it is

The snake the old man the prisoner

My belief is that it is saying

The snake(Satan) seduced the old man (Angela's father) to imprison the woman (Angela)

Let me know if this has been theorized before but i think its the best interpretation for the puzzle because the coins representing the main characters james angela and eddy doesnt exactly fit as well as the former.
