Help Needed 4 Coins

Too blurry to get a proper ID. The top is a denarius, looks to be a fouree (an ancient fake where a bronze core is coated in silver so as to appear like a real denarius). A better picture should render it fully attributable.

The next is an early empire bronze. I cant say who...perhaps Claudius? Who knows.

The last roman one is Vespasian (most likely - it could be titus, but Titus is generally left facing and a little bit...different. Take a look at some Titus and some vespasian coins and make up your mind with the coin in hand).

The final coin is a Byzantine follis. Cant really tell anything further than that.
