I think I found one of interest, hopefully
This is 2007 P Washington Dollar Coin.
The first sets pictures are 3 Washington coins side by side to show the comparison.



The next sets are the Washington coin under magnification next to 2007 John Adams P in better condition on the edge for comparison.

Maybe you could start by telling people exactly what it is you think you found. 😐

It looks like "strike doubling" or "die deterioration doubling". Google those terms and you'll see what I mean. Very common, no added value.

I think he might believe that there is something wrong with the edge lettering?
There is a huge variation in the depth and therefore width of edge lettering on dollar coins. It's not an error to find that.
The potential errors on edge lettering are: missing lettering, partial lettering where the machine skipped, and coins that went through the process twice, in which case the two sets of lettering would be very noticeable.
None of those require a microscope to see.
As i have always said, if you want to find errors, look at more coins, don't look at your coins more closely.
Why does the camptown race song come to mind?
OP, If you found the coins to be interesting, I'm happy for you.
Keep engaged with the hobby if you enjoy it.
Sometimes it's a good way to escape the rigors & stressors of everyday life.
Steve, you don’t know what you like—figure that out. The error thing is gonna get old for you. You’d get far more respect if you posted photos of adding cents to a Whitman folder. Coin grubbing—it’s not a good look. No one who continues to search for errors stays long.
The difference in your quarters is likely die deterioration -- As dies age [and are polished] the devices [numbers, letters, etc.] change the way the coin appears.
If you truly want to learn about errors on coins then visit this site. It is geared towards Lincoln cents, and it will give you a start of what to look for on coins. I would also recommend using a 10X loupe for searching instead of a USB microscope.
Just remember...the advice you receive on the site is worth every bit of what you paid for it.
If you start from the position that every coin you examine should look exactly like every other coin of the same date/mint, you'll find "errors" everywhere.
Looks like machine doubling (or strike doubling) to me. Nice close-up pictures though so OP can't be accused of not providing good enough pictures.
Maybe Mr. Weinberg would be willing to give an opinion on whether the OP's Dollar would be considered an error among collectors who enjoy looking for errors?

Are the pictures not closeup pictures of the coin's edge lettering?

Speaking of the edges, you can't have MD on the edge lettering of a business strike dollar coin.
Don’t encourage him to hold coins that way. Are you a greenhorn too?
I googled it and this is what it pulled up.

Nothing worth bothering with. Dollar coins worth a dollar each.
You’re not required to read what I put in this forum. It obviously bothers you, so why are you chiming in ? Keep the peace
Thank you for your advice. I haven’t been on here very long and I trying to learn. So coin grubbing is what I’m doing?
None of what appeared in your Google search results is the same as “strike doubling” or “die deterioration doubling”, both of which don’t usually result in any extra value.

It looks like a double die error except it’s on the edge of the coin. Is it just me or can anyone else see how the letters look doubled? Not 1955 C doubled or 1969S doubled. Several letters look double the size they are supposed to be. On some of the letters, I see where it was struck a 2nd time but slightly offset. If I’m wrong then I’m wrong, that’s fine.
I’ll start doing that, thank you.
Yes, Your looking though the same jar of pocket change over and over again. Please take those coins and spend them on real errors from a coin show or something. For the sake of this forum please stop posting 'errors'.
P.S. It just makes you look like you have no knowledge whatsoever about coins.

You didn't Google either of the terms I gave you. I think I'm going to stop trying. Good luck to you.

If you had googled what I told you, you'd see that you have what is known as "strike doubling", "machine doubling" or "die deterioration doubling". It is NOT a doubled die. I told you what it was and what to Google. We can't help people who don't want to be helped.

Yes, I was thinking of the drudgery of digging with vague purpose.
It’s not a doubled die error. And, as has already been posted by more than one respondent, it appears to be rather common machine/mechanical/strike/die deterioration doubling of no extra value.. See this site to help learn the differences: https://doubleddie.com/144801.html

I had to open the window and let some of the wrong out.
Great. It drifted in through my open window.

A doubled die is separate from struck twice.
Edge lettering on business strike dollar coins is not struck - it is "rolled" into the edge. There is no chance for a doubled die edge lettering.
Dollar coins that have gone through the edge lettering machine twice have a very different look.
One of your coins has very deep lettering, which will appear thicker than the lighter edge lettering.
Surely, it must be a coincidence that I’ve been hearing a lot of windows being slammed shut in my neighborhood for the past few minutes.😉
Mark Feld* of Heritage Auctions*Unless otherwise noted, my posts here represent my personal opinions.
the machine that imparts the edge lettering on these is called a castaing machine. i'm not sure how the lettering is made on the plate the coin is rolled on.
there is no doubling on that edge lettering
as mentioned the lettering can be different sizes due to different pressures in the castaing machine. you'll notice the bigger lettering is also deeper. i've personally found faint lettering and it is definitely smaller - all due to the pressure.

I googled before you mentioned it.
And then you didn't Google what I told you it was and continued to suggest it was a doubled die.

I don't believe I did encourage him to hold coins that way. To answer your question despite your failure to answer mine, no, I'm not a greenhorn.
