From your images, I think I see traces of an upset rim on the right-hand image and maybe a faint trace of an upset rim between 11 & 1 o'clock on the left-hand image. If I'm correct, then this is a planchet, not a blank. Missing both clad layers, what does it weigh? Personally, I don't know how the clad layer is applied to the copper strip. My Kennedy has a normal obverse. Chris
Now that I look again at these pictures, this could be a planchet. I have them socked away someplace, so we won't be weighing them anytime soon, but I see the traces of upset you're referring to. The edges I recall weren't very sharp, but then this incurred quite a bit of wear before I snatched it out of the $500 box of halves. Yes, I can dx this as a worn planchet, I think, that broke loose after it went spinning around in the upset mill. It's plausible, given the years of wear.
Take a look at the rim in this blank. It's right in the beginning. Stop the video at it. A little further down in the video there's a side-by-side comparison of a cut blank with a milled planchet. On reconsideration, my final answer is, mine is a blank. Don't let the trace of upsetting throw you off, as you can see in this video, that's natural in a blank.
Hey, search "Black beauty coin" and "mid annealed planchet" . I've seen one worth 500, 20 and 0 for damage (side walk coin) I'm a new comer as well, so not giving advice but hope that helps
