Hi I cant seem to find this exact type anywhere online (Wildwinds/Acsearch), any help would be great. Thanks!
Dane has a searchable spreadsheet of Probus issues that can be found here: http://www.catbikes.ch/coinstuff/coins-ric.htm

@bsr045 : Yes, the left and right facing head or bust designations are basically the first few things that you look at on the obverse. Most references start with portrait types, left (typically more scarce for all emperors), right, type of headgear (radiate as you have was typically on antoninianii, where laureate was the gear for denarii), type of clothing (usually bare neck, draped, cuirassed [armored], mantled (fancy robe) and then anything the emperor may be holding in his hands. After you sort out the bust type then look for the obverse legend, reverse legend, type (who or what is on the reverse) followed by mint marks. So if this Probus interests you, you should definitely spend some time on Wildwinds getting a feel for the major types. Your CONCORDIA MILITVM is one of the majors. Dane (moderator at Wildwinds) has that Probus spreadsheet on cat bikes mentioned above which is very helpful. To use the spreadsheet, start on the left side and select emperor, then bust type, so on and so forth to the right. Then you should end up with an RIC attribution. If you are unsure, post here. Take a look at my Probus collection. It's a decent number of coins and yet I'll still never finish getting all of them in bronze and he only reigned six years. http://www.forumancientcoins.com/gallery/thumbnails.php?album=6322
Sometimes yes and sometimes no. In this instance, RIC 666 covers five different bust types - three right-facing and two left-facing. Your left-facing variety is not one of the five listed, so I would record your coin as RIC 666 var (bust type).
The big point here is that RIC V is so out of date that not being listed there is meaningless. When they list 5 or 10 variations under one number (not at all unusual) it is pretty safe to assume there are others. https://www.google.com/search?q=coi.....69i57j0l3.3776j0j7&sourceid=chrome&ie=UTF-8 Fortunately there are a lot of Probus coins online but none of the references will ever get them all. There seems to be several people with interest in the subject so the question is whether any of them will follow through with a book better than what we have online or whether the costs of publication will make this online only forever. There is a great effort online to replace RIC V part one but nothing that organized for part two which includes Probus. The youngest among us may see this change someday. I won't.
Alföldi is the best currently published reference for Siscia and even that is a little out dated with several varieties not known to Alföldi that have come to light in recent year. The following page from probvs.net shows how many variations of RIC 666 were known to him with some additions known to G/< who runs the site. There are more than 80 variations for just this single RIC entry. http://probvs.net/probvs/R666/R666A.html
