Ancient cut coins, Half Asses, man headed bull, Julius Caesar, Octavian and winged horses

I recently won a lot of cut coins to add to my growing collection. I have a box of 50 not well defined Roman Imperial coins headed my way. The collection:

Obverse

Reverse

Left side of page - 
The upper left hand section is Roman Republican bronze coins, presumably Asses. They are worn and encrusted enough that they are hard to impossible to read. I use these coins when I show non coin collectors a coin from 150 BC.

The three coins below the top 7 are -

• The left coin is an As. My best date guess is 175 to 100 BC due to the form of the letter A.
• The middle coin is an As: C. Vibius C.f. Pansa. 90 BC. (25.0 X 17.1 mm, 6.43g, 1h). Rome mint. Laureate head of bearded Janus; I (mark of value) above / 3 Prows right; [ROMA] above; [I] (mark of value) to right; [C•]VIBI•PAN (PAN ligate) below. Crawford 342/7e, BMCRR Rome 2319 - 2320  
• The right coin is a bronze of Octavian. A better pic is here:

Ottavian, Bronze (denomination not on coin), Italy 38 B.C.

Obv - Portrait of Octavian facing right, behind - DIVI F, the coin should have either a comet or CAESAR to the right.  

Rev – [DI]VOS / [IVL]IV[S] within laurel wreath. Part of the legend in off the flan, and the letter S in IVLIVS is missing. Most coins of this type have the S, but the example shown in Sear (RR & 12C) is missing the last S also.

Middle of page - 

The top 8 coins are Julius Caesar and Octavian. There are a few variations in design of the coin, so they may have different RPC numbers.
