Change back from the store. It's been in the coin jar. It's really strange. But what everyone has been telling me here, it's common.
I recommend, for the next 3 months take a look at all the change you receive. And note it's (a) wear; (b) damage, hits, marks, etc; and (c) color. All without posting about it. Maybe categorize them into different containers if you want to keep all of your change for comparison to each other. I think you'll learn a lot about circulated coinage.
Look for metal detecting thread. Then look at the patina of some of these dug up finds. Could very well be one of @paddyman98 finds
Coins not worth anything but 25 cent? What happens when I polish it down to a silver? Tanish and chemical metal fatigue are two separate things...... Thank you all for the expert advise. I'm glad I joined this site. Maybe one day I wont be so naive and wishful thinking.
It could be a 1977 on a 1976 silver planchet but, that would make it an S coin and a 1977 proof, it is neither. How could the silver planchet have gotten from San Francisco to Denver? If it were 40% silver the edge would be white and not show a copper core.
The 77 quarter was discovered with a 76 planchette, so rumors has it , was delivered there at the other location by mistake , and thus making the 77 quarter extremely valuable, if it’s silver , and yes the guys here are correct , the coin must be weight, to tell, but yes 1 quarter has been discovered as of now and was given in pocket change and was sent to professionals to see and test. Turns out a real quarter with a 76 planchette and somehow got delivered to another state at the mint, thus making it extremely rare and now valuable, good find and hope u still have the coin!
