1958-D Lincoln Cent Question On BIE Error

I'm pretty sure that the die used to strike these had worn out to the point that the letter L blended into the rim, so no I don't think that you have a die chip to the left of the L.

I'm leaning toward Die Deterioration Doubling issues.

Agree, this is Die Deterioration Doubling.

Yes, there is die wear between the rim and the L, as there also appears to be on the left side of each letter of LIBERTY. But there also appear to be small die cracks at the top and bottom left of the B, which is what I was referring to.

It is not a BIE as the OP described it. There is die wear at the edges of devices, especially the L, which either makes it look like a BIE to the OP, or perhaps the OP was thinking this kind of wear would qualify it as a BIE (of type ILI).

It is also not (yet) a BIE as I see it, with small die cracks/depressions at the top/bottom left corners of the B, but it's possible this die was on its way to becoming an IIB type of BIE. To be sure, IIB's from 1958-D would need to be examined to see if any of their die markers match with this die.

I've been particularly interested lately in the stages of BIEs, and have been attributing several interesting ones. I recently found the immediate precursor to 1955-S B906, which Cohen did not list. Also found that Cohen's 1955-S BA110-111 and BA114-123 are actually the same die, with progressively later stages. Anyway, it is this interest in early stages of BIEs that made me comment on this thread.

Not a BIE.
