CelticKnot: Notice the area near the '9' in "1965" on the obverse and the second T in "STATES." Also, on the reverse you see "ER DO" in "QUARTER DOLLAR" is flowing towards the clip.

I see it, thanks, BlueSolo. So this is a term related to specific clips or general behavior exhibited by clips?
And who's Blakesley?

Blakesley effect?
The Blakesley Effect, named for the guy who originally studied it, is an effect of uneven pressure during the rim upset because one side is missing due to the clip. In the majority of clips, the opposite rim will be weak. It's pretty clear on the big clip here. The small clip was small enough to complete the rim, if weakly, so no Blakesley Effect. |
