Coin ID Help : Likely Medieval Europe?

Sorry, it's in pretty rough shape. 

No readable date

18.2mm Diameter

1.46g

Obv Lettering maybe *ROLV* and *RE* and *FRR*

Rev Lettering looks like CIVITIMS or CIVITMS other side much less readable

Thanks for any help. 

I think CAROLVS REX FR R, so probably France.

Reverse CIVITAS AQVIINA?

Edit:  Found - N#162648
