The first is a marriage commemorative of Gordian III and Tranquillina--a Roman provincial Pentassarion from Istrus in Moesia Inferior, Moushmov # 198; AMNG (Pick) # 524-525. It portrays "Serapis or Mithras, wearing kalathos on horse pacing right; altar before, eagle on pole behind" and an altar before on the reverse. Here's the listing in Moushmov: And in AMNG (Pick):
The second is a mid- to late-third century antoninianus. Claudius Gothicus maybe? Gallienus, perhaps. It's unidentifiable and nearly valueless.
The third is a limes denarius of the early to mid third-century with LIBERALITAS reverse type. Can't make out which emperor it is. It is similarly valueless.
Ironically, not one of the three is actually LRB, which properly begins with the reforms of Diocletian in the first Tetrarchy. The bronze antoniniani prior to that is technically classed as silver coinage. The limes denarius is of Severus Alexander. You can see the last part of his name which often reads [SE]V ALEXAND AVG. Here the first "A" is at the top of his head.
Ah, yes. He issued several LIBERALITAS reverse types, so narrowing this down further will be impossible.
@Roman Collector Thank you for the detailed explanation. I was aware that for second coin I could maybe find out who is portrayed on the obverse. Thank you for answering @Duane Charter s question for me as well.
@lrbguy That turned out to be so, ironically. I simply did not know, and since my collection is 90 percent small LRB coinage, I thought it was a safe bet to call them like that.
