Old Roman radiate crown coin. Need ID, if possible. [opgelost]

I suspect this coin is circa 200-300ad Roman, but am finding no information about it.  It has a right facing bust with a radiate (spiky) crown, bearded.  The little bit of the inscription I can see is the letters AVG to the right of the bust and it looks like LCV above the head.  The reverse has a figure standing with a sword or short staff in his/her right hand, and a longer staff in the left hand, perhaps a military staff.  Not in the best shape and these are the best two pictures I could get (sorry).  

Any help would be greatly appreciated.

Better photos are needed, especially of the obverse. These are way too dark and blurry. Also, weight and diameter are needed. It's most likely an antoninianus judging from the radiate crown however it could also be a dupondius which is why weight and diameter are needed. AVG just means augustus and is on almost all Roman coins so it doesn't really narrow it down.

Here are some clearer pictures:

Thanks again!

Looks like Gallic Empire to me, maybe Tetricus I.
