Error ID Questions For These... Pennies, 1972 D, 1961 D, And 1974. LMC

@hip, first welcome to CCF. Second, while it is best to open up a separate thread for each coin, this is fine for now.

For the '72-D with the potential die clash, sorry but I can't see this with your current pic. I recommend comparing your coin with others known to be clashed to see if yours looks similar.

For the '61-D, there may be a slight lam that spans the rev. I have tried to enlarge and enhance this area, but a better pic could help to confirm.

For the '72-P that has a wavy obv field, for sure that is damaged that occurred after the coin was struck.

Yes, the first coin is hard to capture. in normal light, I can see what appears to be three faint columns evenly spaced, but it could just be a wavy surface or planchet surface issues. the wear on the coin has made it impossible to tell what it might be for certain. sorry about the photos, I've only got an iPhone at the moment. best I could do.
the second looks like a very thin metal tape strip that runs across the coin. wish it wasn't so circulated.
for the third coin, I suspect the this was die wear just like the trench indentations you see that circle the inner rim of coins, but this wear applies to the un-etched surface of the die. just trying to confirm my suspicions.
I don't want to keep every error or damaged coin I run across. Just the ones that have some value. I've got them piled all over the desk right now, I need space of more! best way to clear out some of them is to ID the ones that don't really matter and put them back in circulation.

thanks! missed that!
