I’ve dug 33 silver quarters: 1 seated, 6 Barbers, 5 SLQ’s, 2 Canadian and the rest Washington. I dug most of these about ten years ago, within three years time.
I’ve dug 10 silver halves: 2 Barbers, 2 Franklins and 6 walkers, also dug within three years time.
About a 3:1 ratio quarters to halves.
Then they dried up.
Losing a 50 cent piece back in 1955 would have been similar to losing a $5 bill today.
What would one buy with a $5 bill today? Most don’t even carry change, but plastic.
A quarter then would be worth around $2.50 today.
A dime, now one dollar.
I believe most silver quarters were hoovered up back in the earlier days of detectors. That, and if someone lost a dime - oh well. Lost a quarter? Eh...couple bucks, look harder for it.
