I hate retelling this to often but, I was the guy that used to collect the coins from all those games and Jukes, for thirty some years, I did post before that I still have well over a thousand pieces in my collection that came from the routes. I still have rolls and rolls of silver,mostly VG or so king George 39 and up to 68.
I had a partner that also collected and he still does and I'm sure he had more than me , he was the main collector. To give you some idea as to how much, we cashed in 1000 each in around I think 1979 and got 10k each.That was a nice score for us.That's about 8000 quarters. I bought him out in 85 and I sold out in 99 by then revenue was up but a lot was in loons my employees kept an eye out for silver for me not much showed up by 1990 even when I counted it myself, by the time I sold out we would count 20000 a week in quarters 80000 coins and I would get maybe 2 my wife and I probably counted 50% of that and the other collectors would turn it in just not much around.
I did find buckets of foreign,slugs,tokens, pounded out nickles, professional slugs sold by the roll for $4.00 or $5.00 for ten bucks worth, these were close weight and had reeded edges.
Found and still have 30-40 proof coins or specimen taken out of Mom or Dads collection.
Had a pretty big operation couldn't take the time to really look if I spotted something as it went through the counter I would grab it. US as well if the spread was favorable, did well on US.
It was fun.
