However, I've had this coin of Carus for a while (a tip of the cap to @Valentinian's website for explaining the significance for dating purposes of coins of Carus with AVGGG, minted in Antioch): Carus, silvered AE Antoninianus, late Autumn 282 [second son, Numerian, elevated to Caesar] to Autumn 283 AD [death of Carus], Antioch Mint (1st Officina). Obv. Radiate bust right, IMP C M AVR CARVS PF AVG/ Rev. VIRTUS AVGGG, Carus, standing right, receives Victory from Jupiter standing left, holding long scepter, star in upper field, A in lower middle field (= 1st Officina, Antioch Mint), XXI in exergue [20/1 copper/silver ratio of alloy]. RIC V-2 125(A), Sear RCV III 12190, ERIC II 141, Cohen 117. 20.25 mm., 3.59 g. [For the dating of Carus’s coins with AVGGG reverse (issued at Antioch mint only), see http://augustuscoins.com/ed/Carus.] And when I recently saw antoniniani of Carinus and Numerian on sale at the same time (from different dealers), both of them in what I thought was excellent condition for that time-period, I couldn't resist buying them in order to reunite them with their father. They've both arrived, so I'm posting them together: Carinus, AE Antoninianus, Feb/Mar 283 [promotion to Augustus] to Spring 285 [death of Carinus], Ticinum Mint [now Pavia, Italy] (3rd Officina). Obv. Radiate, draped, and cuirassed bust right, IMP CARINVS P F AVG / Rev. Felicitas standing facing, head left, left elbow resting on column, holding caduceus with raised right hand, FELICIT PVBLICA; in exergue, TXXI [3rd Officina, 20/1 copper/silver ratio of alloy]. RIC V-2 295, Sear RCV III 12343 (ill.), Cohen 24, Pink [Karl Pink 1949] p. 29, Series 4. 23.6 mm., 3.83 g. [For dating, see http://augustuscoins.com/ed/Carus.] Numerian, AE Antoninianus, Feb/Mar 283 [promotion to Augustus] to Nov. 284 [death of Numerian], Ticinum Mint [now Pavia, Italy] (6th Officina). Obv. Radiate and cuirassed bust right, IMP NVMERIANVS P F AVG / Rev. Providentia standing facing, head left, holding corn ears with right hand over modius at feet left, and holding cornucopiae in right arm; in exergue, VIXXI [6th Officina, 20/1 copper/silver ratio of alloy]. RIC V-2 447, Sear RCV III 12253, Cohen 83, Pink [Karl Pink 1949] p. 29, Series 4. 22.6 mm., 4.15 g. Ex. Pegasi Numismatics, Auction 41, Dec. 11, 2019, Lot 627. [Soon to be formerly] in NGC slab, Cert. No. 5768552-009, Graded AU, Strike: 5/5, Surface 4/5.) [For dating, see http://augustuscoins.com/ed/Carus.] First question: please take a close look at the profiles of Felicitas on the first coin and Providentia on the second. They look incredibly similar to me. Keeping in mind that they're both the product of the same mint (Ticinum) at approximately the same time, how does one explain the resemblance? Same engraver? Same template used for the portraits of multiple personifications at that mint at that time? (I have no idea if that was technologically possible.) But the profiles seem too close to me to be a product of coincidence. Second question: As you can see from the description, the second coin, of Numerian, came in a recent NGC slab. (It wasn't slabbed when it was sold in a Pegasi auction last year.) It's the first slabbed coin I've ever bought, and, in fact, the first slabbed coin I've ever seen close up. Here are the dealer's photos: My reaction to holding a slabbed coin in my hand for the first time: the slab itself is a nice little object, and rather attractive looking. BUT: I'm perfectly serious when I say that I CAN'T SEE THE COIN!! Not really any better than you can see it in that photo of the slab. Maaaaybe, at a certain angle, I can sort of catch a glimpse of what it looks like. But it's not good enough for me. If I had any doubts before the coin arrived today as to what I wanted to do with it, they're gone. So, can someone please advise me on what the easiest way to open the slab (without ruining the coin or the ticket) might be for someone who doesn't want to end up plunging a screwdriver through her hand? It's not as if I have a basement, let alone a basement workshop, but I do have a few basic tools, including hammers and screwdrivers and pliers and a vise I've had since I was about 8 years old, for some reason. Thanks!
