Need Help Attributing Suspected 1787 George III / Irish Hibernia Contemporary Cast Counterfeit Mule

After a few more deep dives of my own, I thought it would make sense to update my last post. So here it goes...

I am looking for some assistance identifying and potentially finding a catalog variety number (Vlack, Atkins, etc.) for an apparent contemporary counterfeit copper coin I have in my possession. It appears to be an exceptionally crude, blundered-die variety from the post-Revolutionary War era. I say "blundered" because the entire inscription and date on the reverse side is completely retrograde, as in mirror-imaged. It is clearly the work of an amateur. The crudely cartoonish King George III portrait on the obverse is also, I believe, in mirror image, and is of the "two eyeballs" error kind, where two separate eye profiles are stacked next to each other. Additionally and upon further review, the coin appears to be a contemporary cast piece rather than struck. There is a clear, unfiled casting sprue/gate remnant protruding from the rim, along with a corresponding soft molding flash line around the edge.

Given the 1787 date, specifications (i.e., 8.31 grams, slightly more than 30mm diameter), and extreme crudity, I wonder if this coin can be linked to the kinds of clandestine operations that were rampant during the 1787 currency crisis. Or, perhaps, to American/Canadian Blacksmith style issues.

Has anyone seen this exact "two eyeball" obverse paired with the mirrored 1787 Hibernia reverse before? Any catalog references or insights in general would be GREATLY appreciated!
