Some coin shops run auction boards…
As a kid I took $50 I earned and exchanged it for $50 sacks of pennies and go through a sack each week… I was 8 when I started.
The bags probably sat at the BofA vault in Oakland for decades and yielded lots of wartime steel and even some Indian Head plus S mint mark for San Francisco mint fairly common…
Dad said it kept me out of trouble…
4 years in High School I was cafeteria cashier and picked up silver dimes and quarters regularly.
Most just bullion value and all circulated but it was fun filling the coin books.
I started saving the 40% 1965-70 half dollars but it was a lot to put away for a kid earning $50 a week.
I found selling it’s the exception to get anything over bullion…
My one $20 gold coin was worth $400 when I gave it to my uncle who would not take anything helping me build the cabin… I gave him the coin and he was really impressed at the gesture…
Picked up some Carson City Dollars and Silver and Gold certificates plus wartime Hawaii Bills over the years.
The bank teller thought it cute I was collecting and would set aside special notes that came in.
The Branch President always called me Mr. and said one day I would own the bank starting so young… that BofA now a church with outreach ministries..
For years I gave US $5 gold coins to the nephew and nieces until their parents told me to stop saying it was too much of a burden on the parents… go figure… I was buying at $37 when I started and just couldn’t see the value of another Barbie Dream House or Ken Corvette…
