1999 Connecticut D State Quarter No Reeded Edge Error?

@ck8, first welcome to CCF. Second, those pics are fine--well above average for a first-time poster.

Finally, I agree that this coin didn't leave the mint with the edge looking this way, but rather someone has removed it mechanically. A good website to learn more about mint errors is error-ref.com (although of course we'd love to have you hang out here too).

I'll throw the early stage dryer coin theory into the mix.

PSD and it would be impossible for it to be a Dollar planchet. Why? They are not the same weight or diameter and the fact that the quarter is nickel clad, the Sacagawea is not nickel clad.

Sorry, Charlie. I think just about everyone who's taken up this hobby has had the experience you're having right now of incredulity when everyone tells you the thing you're *sure* is an error is just PMD. That said, I can assure you that is what it is (and definitely not a sacagawea planchet, which would be a completely different color and wouldn't have the copper core). You'll develop the eye for what is an actual error and what isn't as you find more real error coins and read more about what errors are possible and what they look like.

Except there would be no way to know whether the weight had been reduced. I put a quarter in a lathe and just take off the reeds I would reduced the weight by >.1 grams, probably significantly less. And since the tolerance range for the quarter is +/- .227 grams you have no idea what the weight of the quarter was when I started and the weight removed is much less than the tolerance weight. So unless I started with a coin at the bottom end of the tolerance weight, 5.44 grams, the altered coin will weigh within the tolerance range.

There is only one way for a quarter to leave the mint with a plain edge, and that would be if it was broadstruck, and in that case you would not have that flat edge with sharp corners. (I you look at the edge of a planchet you will see that it is NOT flat to begin with, so when it is struck without a collar it definitely isn't going to be flat afterward.) Even if you had a press with quarter dies and a plain edge dollar collar you wouldn't get the OP coin. The collar is significatly wider than the planchet so it would be unlikely to reach the collar all the way around, and evenif it die the resulting coin would be noticeably greater in diameter with very wide rims. Note how wide the rim is on the quarter side of the Sac/quarter mule. That is what the rim would be like on a quarter struck in a dollar collar.

To the Forum.

I'm still trying to figure out how all this works...Charliesk8...I tried to email you but the thing says I can't... but somehow we need to talk about our coins because I have a coin just like yours but a 1993 I seen your quarter on here it's the only other one that I seen is almost exactly alike but different years. I see that your coin has a dent in the top of the rim...I looked at mine because I have the same little indent but at the bottom but that looks like it was pressed into the rim when it was made...I have some pictures on my profile on here but you can see the details in my coin but I think we need other to prove what our coins are... Error coins. I tried to spoon a quarter but I showed what happens when you do that... dryer coin... the pictures I seen of those..they look like they were ran through a washer. But I used some of your pictures because your quarter is the only one that I found on here that's just like mine...I would like to talk to you but I don't want to put my phone number on here but I think we can help each other

This looks like a vending machine quarter. From my understanding thus is an extremely common occurrence with Arcade/Vending Machine/Laundromat quarters as they take a veritable TON of abuse over their years of service.
