Help with silver dollars

[justadood]

I ran into some silver peace dollars. First and foremost, I'm not selling or meeting people on here. Won't be scammed. But I'm trying to figure out I guess first, what are they worth, who do I contact to possibly get them valued, any information will be helpful. Here are what some of them look like.

The first step is to make a list of the ones you have by date and mintmark.

The mintmark on a Peace dollar is found in the lower left of the reverse, between the tip of the eagle’s folded wing and the rim of the coin.

Then check the link above to see if there is anything that might be valuable.
