Help with ID of 2 Roman Coins

Greetings.. I couldn't recognize the Emperors' names nor the very interesting reverses of
these two Roman bronze coins. I wish you could assist me to identify them. Thank you.

Top looks like severus alexander, bottom looks like Aurelian, hard to tell from the pic.

 

Try posting clearer images. It's rather difficult with the blurriness.

 

Here are better scans. Hope they do.. Charles

 

Mat nailed it. S. Alexander and Aurelian. LIBERALITAS AVG and ORIENS AVG types.
