Late Roman bronze coins, 4th century AD. On the first coin there's enough to see it's from either Constantine the Great or one of his sons, but I can't read the crucial letters to narrow it down. Not sure of the emperor for the other one. I can't be sure based on the photos, but it doesn't look like anything very valuable here, no more than $5 each. You can get lots of other opinions if you post over in the Ancients section, and you will get better answers if you can post clear, well-focused photos of each side for both coins.
