Earlier this year I was searching and sorting loose change for a service business I operate in. There were 3 rolls that someone gave to pay for service. This was one of those rolls. Take nothing for granted.
For the most part I have given up on buying coin from most banks - I get mine from credit unions where they are just pleased as punch to sell it off with the promise it won't come back - see when they have to ship it out to a coin counting facility it cost big money.
I was getting some candy from a vending machine once and the dime I had kept dropping out of the machine into the coin return. After 3 tries, I inspected the coin to see what was wrong. It was a 1948 Roosevelt. I never would have noticed it had I not tried the vending machine. So silver coins do circulate occasionally. I also get Kennedy halves at the bank and I usually find at least one 40% silver every couple of rolls or so. But does Kennedy half count as a circulating coin?
I found 9 more! Last night at work 2 different customers in a row paid for their merchandise with coins, including a bunch of dimes. The first customer was tossing the coins on the table when I heard the unmistakable sound of silver hitting the counter. I noticed that several of the coins were dull and tarnished and my heart started racing. I looked through the dimes and found 4 silver dimes. The next customer also paid with many dimes, and I saw the same tarnished silver that I had just seen. I pulled 5 silvers out of this pile. I've now found 24 in the last month. The dimes are from 1951, 1952, 1953, 1954, 1956, 1957 (2), 1958, and 1960. Amazingly, I didn't find any 1964s. Of the 15 that I found a few weeks ago, about 8 of them were 1964s. All of the dimes are dull and quite tarnished, and the '56 is bent. This was my most successful find so far this year.
I agree that silver can be found in limited numbers in dimes. I buy rolls from my local bank and they have both cwr and plastic wrap dimes. In the past years I found enough silver to keep me coming back. On the other hand, I also find halves but mostly 40%ers (still free silver) however, I have not found any silver in quarter rolls.
I was lucky when I was a kid, in 1969, 5 years after they stopped minting silver, I got a job at the school helping to sell the stacks during lunch. I started pulling out silver, as much as my allowance and tiny pay check for helping at the snack table could bear. I wound up with a couple of fairly nice, half full albums and a jar of silver dimes and quarters and a handful of halves. A year's worth of all my $. Didn't even buy comic books that year. I still like to roll search, but I don't do too many dimes, as its hard to see the tine dates, but I do usually 10 rolls a month and of course pocket change. When I do 10 rolls, I don't always find any silver, but sometimes I find one. So I'm guessing 2 per 50 rolls sounds about right.
