I see what you believe to be a "7." My thought was that if it was a seven, it would be raised like the other "7." It does not appear to be. Also, if this was a genuine repeated "7," then there would be other quarters with the same error. After 46 years, it seems that this would have been discovered by now. Because it has that orange stain, I believed the "7" to be just pareidolia, as SensibleSal66 suggested. I know varieties can be discovered years later, but that would be a major one. I sincerely wish you the best, and Happy Coin Hunting!
...a chance to pick a fight, apparently. And then cry about being a victim when someone blocks your punch. Sorry.
I think it’s amazing when someone can pull out the most smashed and abused coins and then proceed to point out certain errors made at the mint 50 years ago. And yes, most of time the answer is going to be send it in, let the experts look at it and give you a professional opinion using facts after they have examined it using tools made for the purpose. I would not personally buy any “error” coin that hasn’t been graded. lighten up Francis
I especially liked the part where he preemptively set the "rules of engagement" to exclude anyone recommending that he submit the coin for an expert opinion. I don't want to beat a dead horse, but in case it's helpful to someone else who runs into this thread, the first thing you need to do when you think you see something, other than knowing what's possible for the mint to have produced during the era when a coin was minted, is to eliminate nearby digits or numbers that cause your brain to recognize a pattern that isn't really there (aka pareidolia). What do you see now? Did the mint also put a question mark on the coin, or is this just random blobs of corrosion? Now rotate the image 180 degrees. See anything besides corrosion?
It's got an L on it, plain as day, one-third in from the left and bottom of that last image! Clearly the letter fell off an 1864 cent, lurked in the crevices of the Philadelphia mint for 130-odd years, and then flung itself onto this quarter. Who could put a price on that?
