Coin 1 seems to have marks on both sides of the coin that completely got rid of the denticles, as well as parts of the letters. Not even sure what to guess on this one. Coin 2 I only have one picture of because it’s online, is it just a large die break in the rim or struck through something potentially? Apologies if the picture isn’t high enough quality to tell. Coin 3 is the wheat penny, I was thinking lamination issue but would that make the letter B as wonky as it is? Thanks!
Coin 1 looks like a grease filled die, Coin 2 looks too blurry for me to say, Coin 3 is a die chip. I’ve been at my antique shop for 9 1/2 hours today so things are a little blurry but that’s what it looks like to me.
Coin 1, I'm going to guess a defective planchet, as @ToughCOINS mentioned above. Coin 2 reminds me of a cast coin that didn't get enough metal, so not sure. Coin 3 Die issue of some type. Being irregular and having that straight line is a bit confusing to me, so not sure. To summarize: What do I know?
