The lettering above the horse should identify the issuing authority. Look for Philip in the Greek alphabet. It's probably Philip II, the father of...
I agree that they should have taken the coins out of their plastic holders to photograph them. The glare makes some of them hard to see. But as...
Yeah, the Thessalonica one is interesting: one captive, seated, emperor holding Victory, no shield. Yet wasn't it issued at the same time as the...
I agree that it's Cyzicus.
If the back is blank the coins are probably just replicas, not genuine.
We'd need better pictures. If you really want useful help then get into the habit of taking the coins out of their holders, photographing both...
Whichever coin you get, his portrait must absolutely show off his crazy, punk haircut.
I wouldn't know about eBay in Australia. I live in the U.S. 225g of SSC costs $10 plus $3 shipping. I'm pretty sure you won't need 5 lbs of it....

[IMG] Billon Antoninianus Cyzicus mint Obv: IMP C AVRELIANVS AVG Rev: ORIENS AVG - Sol, standing left, rasing right hand and holding globe in...
I think $2-$3 each for these coins would be a fair price. The ones labeled "3rd-4th cent" are 4th century, probably all sons of Constantine the...
#1 - Yes. Especially Antoninus. Marcus and Aurelius also appear frequently, but are easier to figure out. But the easiest to mix up are Maximian...
