BLAKESLEY EFFECT - must it be present on clips for the clip to be authentic? example inside

LanceNewmanOCC

.
with either minimal or virtually no b-effect to be seen, is it possible for a clipped coin to be authentically clipped?

i say yes, but i do not set the rules on coin minting and physics

It is not required for a clip to be authentic. Your coin is a good case in point. No Blakesley, but a genuine clip.

Agreed to both points.

One possibility is an incomplete clip blank that has all the metal when the blank goes through the upsetting mill, so that there is no void to create a Blakesly Effect opposite it, but where the stress of the upsetting process causes the incomplete clip to break off prior to the strike.

As others have said, a Blakesley effect is not required. There are several other diagnostics indicative of a genuine clip:

1. Fadeout and taper of the design rim as the latter approaches the clip (your coin shows this).

2. Metal flow in design elements bordering the clip.

3. A "cut-and-tear" texture on the clipped edge.

No.

I look for metal flow.

BLAKESLEY EFFECT since this is used as proof of a authentic mint error clipped coin the fact that it is not visible might also be used as proof that the coin is clipped just maybe not by the minting process.

I kind of think it would be hard to trace the coins ownership and condition back to the mint at this point in time.

Blakesley effect is not always present on genuine clips, at least to a degree that is easily visible on a worn coin. This is especially true on nickels, which are made of a harder metal than copper or clad coinage. Other diagnostics like the ones Fred listed are still useful and valid even if the rim weakness opposite the clip is not present. Your coin, for example, can be attributed as a genuine clip based on metal flow alone.

That said, I do see a subtle sign of Blakesley on your coin, which I've highlighted in the image below. The rim noticeably becomes weaker at the point I circled.
