1983-P Dime W/ "Wrinkles" Covering The Reverse & Thick Sloppy Lettering

So what you're saying is its one OF a million not one IN a million & I still have to go to work on Monday LOL that's fine I have a container full of questionables that I've been setting aside and wrapping individually just in case one of them turned out to be worth something I'd hate to degrade the value due to clinking up against other coins. I know I do have one legit one but it's nothing fancy just a "BIE" penny. But thanks for the info I've learned quite a bit about this little Hobby the one thing I've learned most is I don't know much LOL

I have a 2017 District of Columbia State Quarter that has some unusual markings. I don't have a good picture right now but I'll give you a brief description tell me if any of them sound familiar if you would please because I can't find anything on it. In the date "2017" the "1" was stamped on top of a sideways, lowercase, letter "i" & then on the obverse in the center of the base of Washington's bust, (left of the engravers initials) there is the bottom portion of possibly the letter "T" or "I". All I know is, that it is a part of a letter & it is not supposed to be there. I just don't know how or why. I'll try to get a good picture of it tomorrow & upload it

E&V is correct about Die Deterioration. Those "wrinkles" you referenced are called "die flow lines." The planchets slowly erode the die as they're being struck. The flow lines are caused by the planchet's metal flowing radially outward during the strike.
