Before I mark this as a cull I just want to confirm that it’s not a clipped planchet or some sort of error. TIA
Ask the error experts: @Fred Weinberg; @mikediamond; @furryfrog02; @paddyman98; @desertgem; @Michael K; @JCro57; et al. I think they would like to see clear photos of the edge and clearer photos of both sides of the coin. (IMO Your photos appear to be too bright to see any details).
How does one determine damage or error on this? Looking at http://www.error-ref.com/_straight_clips_/ and the number of decades that coin has seen I am curious what the telltale signs are.
I would think one thing that would be a tell is that with such a severe clip you would see a fairly clear Blakesly effect even when this worn. https://www.australian-coins.com/error-coins/how-to-determine-if-a-clipped-planchet-error-is-real/
No Blakesly effect on the opposite side so it's damaged. Been ground down to look like a straight clip.
However with a clip this size, it's hard to rationalize how it could escape having a Blakesley effect.
The percentage is overwhelming in favor of the Blakesley effect and it's as @Kentucky stated, too large a coin not to show.
I've actually found that perversely the Blalesley effect for some reason is more likely to be missing on large clips than on small ones.
When a blank is cut out of the edge of the strip, that is a finished edge - it comes from the cutting of the metal that made the coil or sheet. When a tool is used to 'create' a fake clip, it always has a slight bevel - even a 'flush cut' pair of wire cutters have a tiny bevel. Normal cutters have a fairly substantial bevel. You can see the effect on the very edge of the cut... it's not square.
