1968 no "s" dime

I was give a piggy bank my grandfather recently and it contained nothing but dimes. I went through them
And found some old mercury dimes and also 12 1968 dimes. I know that most 1968 dimes without the "s"
were from Philadelphia but I thought maybe someone with more knowledge could tell me if any were proofs.

Unfortunately, there are no proofs in the bunch.

Proofs have a squared rim, and the business strikes have rounded rims. Those all have rounded rims.

The proofs will also have a mirrored finish as the planchets are polished in a drum with steel bearings, and a mild cleaning agent mixed with water. The drum is spun around the the bearings are what polish to the surface of the planchets to a mirror finish.

 

Here is a picture of some of the other coins I found. 1935-1945

 

Any of these have value?

 

If you are refering those dimes from 30's and 40's then yes most definatley! They are made of 90 percent silver and each one is worth right around $2

 

Thank you
