I like local coin shops. Let them know what your doing and they should let you pick out your own.
An easy calculation to see how much over spot your paying for 90% silver U.S. dimes, quarters and half dollar coins is:
.715 x face value x silver price = value in silver
For example, if you are buying 6 silver quarters and 12 silver half dollars, that equals $7.50 in face value. Today’s silver price is $17.20. So that silver is worth:
.715 x 7.5 x 17.20 = $92.24. Anything over is the premium the shop is charging for their profit. They also buy below spot for their profit.
Morgan dollars are different though. They are about 24 grams of silver. These coins carry numismatic value (value through rarity) and usually sell per coin from $17 – 30$ depending on quality. Look for feathers on teh eagles chest on the reverse for wear. Here’s a good video showing ho to pick coins. :

I also go to APMEX.com They have a great selection. Sometimes a little high in price but they always have something:
