I like his ID.... "Lawn ranger", as in he uses lawn tools to slice and dice the coins?

Watch for the smaller sliver to be sold in another auction.

If a clipped planchet goes through the die press, the area on the edge of the clip show's a rounding off. The edge is never square as the metal flows into the clip and not the die surface. Additionally, the Blakesley effect, which sometimes appears but not always, will show a weakness in the strike directly opposite the clipped area.

Good diagnostics can be read in this thread.

I don't understand. I can clearly see the Blakesley effect in both photos.

False alarm, Lee, that one is good. There is Blakesley Effect visible on the reverse rim opposite the clip, and faint metal flow at either edge of the clip is visible on the reverse as well.

I'll admit I'm at an advantage as I have a few genuine Sacagawea clips in my colection which I have examined closely. I'm not sure if it is the metal or the design of the rim, but the diagnostic metal flow at either end of the clip is very subtle on these. The first one I bought had me on the fence until I could examine the edge inside the clip, which showed the cutting-tearing you would expect from a real error.

Why the squared edges Sean? I was certain that there would bve some rounding where the metal could not flow into the die. Plus, that Blakesley effect looks a bit off. Almost like an intentional hit.

BTW, I changed the title of the thread.

I'm just not certain about this stuff anymore.

On larger clips (on the order of 15-30%) the metal flow can be very hard to see. I'm honestly not sure why, someone with a head for metallurgy and geometry could probably figure it out. Here's a poor picture of the 2000-P Sacagawea clip that I was discussing in my earlier post, even in the hand the evidence of metal flow and Blakesley are subtle at best. Only by examining the rim inside the clip could I positively attribute it. I've since seen enough similar coins that I'm familiar with the look.
