Better pics of both sides of the coins in question would certainly help....Can't see quite enough detail to tell. With better pics, it will certainly narrow it down.
Is it the same size as a small cent or large cent? If it's the same size as a small cent, my guess would be a flying eagle cent, just based on color and thickness. Awesome finds regardless!!
Yea the one on the left is a large cent. The one on the right is the same roundness but a little thicker. And the words united states is bigger. That's all I can see on it. Grrrr. Lol someday i Hope I'll pull one out that looks better.
A picture of the other side still might help. If not, you could always try taking a pencil rubbing of the obverse of the coin. Might produce some detail... I had some trouble seeing the date on a draped bust large cent that I found a few years ago but then I took a rubbing and here's how it turned out.
