Why is this coin special? (VERY special!)

[dougsmit]

I'll propose a term yottaderp for worse than can be imagined.  I suppose that would include slugs of the lowest order that even a specialist could not love.  I believe the one here is the worst coin I ever purchased separately but it never got accessed into my collection.  It came back in the early 90's when I was new at Alexandria mint denarii and was overly impressed by the fact that the type was not recognized by RIC/BMC.  It turned out that these were the most common of Julia's Alexandria mint types making it the worst $2 I ever spent on a coin.  Perhaps under 2022 standards I might describe it and about VF portrait???
