First is an Alexandrian tetradrachm of Probus, Year 4, 280 AD. It's in decent shape and should be worth at least $15-20.
Second is a posthumous commemorative of Constantine, showing him in a quadriga reaching up to the Hand of God. It is in excellent condition and is worth a decent bit - most are struck on small flans with incomplete legends. Generally these are common in lots and only worth a dollar or two, but I would imagine this would easily fetch $25+ on ebay.
