Hello! A few days ago I found this coin. I was wondering if this could be a die clash. Could it also be a DDO, or do you think it is just machine doubling? Do you have any ideas?

Thank you!

The line behind Lincoln could very well be from a die clash, but everything else you are seeing has nothing to do with it. 

Die clash behind Lincoln. 

Yeah, that's a die clash all right. The doubling your seeing is just strike doubling I think.

Thank you everyone for sharing your thoughts on this coin!

Hello! I have another coin here. Is it just me, or is this a DDO? There is some doubling throughout the obverse of the coin, but it is most noticeable at the date. I found this in a roll of uncirculated coins, and I have many of them. Thank you!

In my 30 years of experience I would say DD. But I'm not the grader.  I will also say the Denver mint has more errors than any other mint. Some big ones also! Thanks good.shots!

If this is a DDO, what do you think I should do with these coins? I can't find this coin anywhere else. I also have some other pictures of different parts of the coin if you think that may help in the identification of this coin. Thank you!

I have recently received a 2022 proof set, and I believe there is a strike through on the reverse. What do you think? If it is a strike through, is it major enough that it would be worth more than the regular proof dollar? This coin is still in its mint packaging. Thank you!

While by no means an expert, commenting on similar errors I've seen over forty-five plus years, it appears to be both. Doubling of the letters and a die clash, the columns of the Memorial reverse imprinted on the obverse.
