People buy and sell silver dimes by the pound, not per coin...or so I’m told.
The average bag of 90 percent junk silver contains 715 ounces of pure silver (after accounting for wear). $1000 face value dimes and quarters are currently trading around $11980, which means you are paying $16.75 per ounce of silver. Silver is currently selling on the spot market for $13.74, which means you are paying a $3 per ounce premium or about %22 which is quite high. My belief is you buy silver at the cheapest premium you can. You can buy 1 ounce rounds from an outfit called First Majestic Silver, direct from the producer, online, at $1 per ounce premium, one of the lowest premiums around. They limit your purchase to 200-300 ounces per purchase, but they are honest and ship pretty quickly, depending on demand. They are publicly traded on the Frankfurt exchange TSX: FR and operate out of Canada. I have ordered from them a lot and they have fulfilled orders flawlessly. A first rate operation.
All silver coins are struck in 1964 or earlier with 90% purity. Each bag contains either all dimes, quarters, or half dollars. No mixed bags. For all dollar bags, call for price and availability. Full bags with $1000 face may be shipped as 2 sealed half bags.
Don’t buy dimes.
