I was dumping dimes this morning at a TD bank, and when the machine was open for them to change the dime bag I noticed some silver halves in the half bag. There were hardy any halves in the bag, but most looked silver. I had halves in the car that were ready for a different dump bank, so I asked the girl if I could swap some of my halves for the ones with the white edges in her bag that I collected. She said she would ask her manager (usually not a good sign), and I thanked her and went to get the halves from my car to speed up the process in case the answer was yes. When I came back in the bank (I was gone less than 1 minute), she was going through the bag to help find the ones I needed. In that short of time I figured there was no way she asked anyone if it was OK, but I wasn't gonna bring that up. Here is what I got for $6.50:
1942 Walking Liberty
1943 Walking Liberty
1950 Franklin
1952 Franklin
1953 Franklin
1962 Franklin
1963 Franklin
3 - 1964
1 - 1966
1 - 1967
1 - 1968
And a 1964 quarter from the return tube of the machine.
It's weird that the machine would reject the silver quarter, but accept all those 40% and 90% halves.
