Hi, Keven --
It all depends on the dates and condition of the coins. I urge you to check each of the dates and mintmarks on your silver dollars and compare those against the listings here at CoinValues, looking for the more valuable issues.
Morgan dollars:

Peace dollars:

As you do this, bear in mind that it costs between $20 and $35 per coin (sometimes more) to get them certified -- meanwhile, common-date circulated Morgan and Peace dollars are presently worth around $17 to $20 each... I suggest only certifying those that are worth at least $75 to $100 or more each, including rare regular-issues, higher-grade material, and special or unusual varieties.
Good luck,
Josh
