Went to credit union I wasn't a member of. Asked the teller if he had any half dollars and he said no. He then asked the other tellers and they had none. As I turned around and walked it he said wait, I have a roll and a half. He said he forgot about them and they had been there for a long time. Of course I bought them and they ended up being all silver!
I found someone's collection once. 5+ rolls of 40% halves , several rolls of 1974d Halves (no ddo) and a dozen rolls or so of bicentennial halves. All rolls were labeled with a marker and cane out of a box of $500 from the bank. And get this... it was my FIRST ATTEMPT at finding silver at a bank. Beginners luck for sure!!! it was only a ouple months ago, I posted pics when it happened.
First, full disclosure: I work at a credit union. The tellers were bagging coins one day and asked if I wanted to help as they know that I like coins. I got to the second rack of dimes and saw ten rolls wrapped from a bank that hasn't existed in 35-40 years. They were solid silver--mercuries and Roosies. It was the best $50 I have ever spent.
Not mine, but my dad found a VF 1909-S Lincoln. Personally the best I found was probably a pretty nice 1909 VDB.
I bought $1000 in mixed cents from the bank, searched them, kept the nicest ones in a book, turned in the remaining $600 of crap cents for more mixed, searched them, turned in the $400 remaining cents for more, searched them. Found a silver Roosevelt worth $2.20 and a bunch of older Lincoln, 1918 1919 1928 etc. Found a steelie, nothing in great condition, I think the most valuable cent was $20, epic week of looking at tiny coins. My head hurt so bad
Late Jan.2017, got 1-box dimes MWR's, with 98-silvers of (33-Rosie's, 65-Merc's). Best box prior to that was 18-silvers about 3/4 years ago. I'm still stoked with the 98-dream box.
