5 to 10 bucks each for the 2 slabbed ones because I am assuming there's no silver or gold content. The Kennedy half dollar is always worth melt valve. Can't tell the grade from the photos but it looks circulated.

Not with those photos

Cool coins. I love early USA copper. Do you know what to ask for these?

First thing, you need to post a price to get folks interested. If you need help coming up with a price we can give you some ideas but best to look at guides and see what they say as well as taking advice from collectors and dealers with experience.

You also need better photos. It's hard but they won't sell unless you get clear photos of the obverse and reverse.

metal detector finds?? large cent and small cent need an expert. HIGHLY corroded. And a east india coin??
