Hello everyone. I picked up a lot of barber dimes and I ran across this 1912. I am assuming this is just some form of post mint damage. But I have never seen such a circle that caused a recess within the entire diameter of the circle.

Hello all, I am well versed in common rare and valuable US FR notes, such as fancy notes with repeated digits, radial patterns, Trinaries, etc, and have sold a few repeater bills to my local numismatic shop for a solid profit. Rarely do I ever see any bill older than the 90’s, especially a $20 out in the wild, so I figured I would consult you folks if ya have any info on possible value, whether if it has any numismatic or collector value that would be awesome to know, or if it’s just worth face or not worth selling ($22-$24 value, would be easier and smarter to just spend it as a $20) anything is appreciated!

I see there is no online database from Valcambi to search their serial numbers. But does anyone have any idea when this would be from? Not sure how many they make per year but feels like a pretty low SN to me. Does this add any kind of collectors premium to it?

A quarter fell out of a vending machine after I paid with card and it's almost fully black and won't rub off, is this a print error or just natural wear and tear?

Picked up a Nazi Germany 6 Reichspfennig and a 1943 German 1 Reichspfennig coin.

Also ended up getting this 1939 silver German 2 Reichsmark
