@Severus Alexander to make this thread, so I gave it my best shot. This is my 3rd year of coin collecting and I think it may have been my best year. I sold many of my early Roman Imperial coins that I got in the previous years, and turned my focus to mainly coins of the Tetrarchy and Byzantine coins. Without further ado, here's my top 10 list for 2019. #10: This is one of my favorite over-strike coins. You can see the under-type on both sides (that I am yet to identify), and the die for the new coin was small resulting in the flan folding onto it upon strike. This creates a pretty cool effect on the edges as you can see in the picture. Constans II AE Follis 659 - 668 A.D., Syracuse Mint 4.07g, 27.8mm, 6H Obverse: -, Constans, holding long cross, and Constantine IV, holding globus cruciger, standing facing Reverse: TKw monogram, Large M; monogram above, Heraclius and Tiberius standing facing to left and right, respectively Exergue: SCL Reference: SBCV 1110 #9: This one is ex. @TheRed, and its my first example of the series of huge Justinian folles from the Cyzicus mint. I am always impressed by the size of these coins and always wonder about the impression of the Romans while handling these coins in their day-to-day purchases. Justinian the Great AE Follis 542 - 543 A.D., Cyzicus Mint, 2nd Officina 19.765g, 39.4mm, 6H Obverse: D N IVSTINIANVS P P AVG, Helmeted and cuirassed bust of Justinian I facing, holding globus cruciger and shield decorated with horseman motif; cross to right Reverse: -, Large M; A/N/N/O - X/ς (R.Y. 16) across field, cross above, B below Exergue: KYZ Reference: SBCV 207 #8: This is a common coin from the London mint. The depiction of both Constantine and Sol are very good, and the coin is struck on a large and circular flan with very few missing details. I am especially fond of the rendition of Constantine's nose on this one, although I doubt it would make the cut for the "Crooked Nose" challenge thread. Constantine the Great AE Follis 309 - 311 A.D., London Mint 4.65g, 22.80mm, 12H Obverse: IMP CONSTANTINVS P F AVG, Laureate and cuirassed bust right Reverse: SOLI INVICTO COMITI, Sol, chlamys falling from left shoulder, standing left, raising right hand and holding up globe with left hand Exergue: T/F//PLN Reference: RIC VI Londinium 121a, Cloke & Toone 6.02.010 #7: When the engraver was working on the obverse legend,it looks like he thought he was running out of room at first, until he was done 'MAXIMINVS', then realized he has a lot of room to fit in the 'NOB CAES' resulting in the legend we see here. Along with the hints of silvering, and nice brown patina, this coin makes it to my top 10. Maximinus II Daia AE Follis 308 - 313 A.D., Alexandria Mint, 6th Officina 6.730g, 23.1mm, 12H Obverse: GAL VAL MAXIMINVS NOB CAES, Head of Maximinus Daia, laureate, right;ties divergent, with pointed truncation Reverse: GENIO CA-ESARIS, Genius, wearing modius, nude, chlamys draped over left shoulder, standing left, holding patera in right hand and holding cornucopiae in left hand; liquid sometimes flowing from patera Exergue: K/(ς on P)//ALE Reference: RIC VI Alexandria 99a #6: There is something really special about this coin and I can't understand why it is so. There are two distinct representations of the letter 'A': one in the obverse legend and another, more familiar representation, in the mintmark. Also to note, Constantius does not have a flowing beard in this representation of him. Constantius I Chlorus AE Follis 296 - 297 A.D., Heraclea Mint, 1st Officina 8.39g, 29.0mm, 12H Obverse: FL VAL CONSTANTIVS NOB CAES, Head of Constantius Chlorus, laureate, right Reverse: GENIO POPV-L-I ROMANI, Genius, wearing modius, nude, chlamys draped over left shoulder, standing left, pouring liquid from patera in right hand and holding cornucopiae in left hand Exergue: -/-//HTA Reference: RIC VI Heraclea 18a #5: This one was a recent win showing very detailed portrayals of both Diocletian and Genius. At this time, coins minted in London began to show enlarged busts. This one shows an enlarged chest area, but the head remains small. I am still looking for an example with the enlarged bust. Diocletian AE Follis 296 - 303 A.D., London Mint 9.49g, 26.0mm, 6H Obverse: IMP C DIOCLETIANVS P F AVG, Laureate and cuirassed bust right Reverse: GENIO POPV–LI ROMANI, Genius standing, facing left, head surmounted by a modius, naked except for chlamys over left shoulder, holding patera in right hand and cornucopia in left arm Exergue: -/-//- Reference: RIC VI Londinium 6a, Cloke & Toone 2.01.003 #4: This coin was missed by RIC, and is fairly common. Its a coin of Constantine as Caesar minted in Antioch. The style is very similar to coins of the other Tetrarchs from around the same period of time. Constantine the Great, As Caesar AE Follis 306 - 307 A.D., Antioch Mint, 1st Officina 10.40g, 26.0mm, 6H Obverse: FL VAL CONSTANTINVS NOB CAES, Laureate head right Reverse: GENIO POPV-LI ROMANI, Genius standing left, modius on head, naked but for chlamys over left shoulder, liquors flowing from patera in right hand, cornucopiae in left Exergue: -/A//ANT: Reference: Not in RIC #3: I have a few Constantine Rome Mint Soli Invicto Comiti coins. This was a break in the tradition, a Marti Conservatori which I'm sure @maridvnvm would like. Its a nice coin with some residual silvering remaining underneath the bed of verigris. I would try to remove the verdigris if I knew how, as the details on both Constantine and Mars seem exceptional. This definitely is a worthy bronze winner. Constantine the Great AE Follis 313 A.D., Rome Mint, 2nd Officina 3.24g, 20.0mm, 6H Obverse: IMP CONSTANTINVS P F AVG, Bust of Constantine I, laureate, draped, cuirassed, right Reverse: MARTI CO-NSERVATORI, Mars, helmeted, draped, cuirassed, standing right, holding reversed spear in right hand and resting left hand on shield Exergue: R/F//RS Reference: RIC VII Rome 6 #2: Coming in for silver is this beautifully silvered coin of Galerius as Caesar from Carthage. It has a beautiful depiction of a lion on the reverse with Africa wearing an elephant headdress. If you look closely, you can see the details on the elephant's trunk. Galerius AE Follis 298 A.D., Carthage Mint, 4th Officina 8.24g, 28.0mm, 6H Obverse: MAXIMIANVS NOB CAES, Head of Galerius, laureate, right Reverse: FELIX A-DV-ENT AVGG NN, Africa, wearing elephant-skin head-dress, draped, standing front, head left, holding standard in right hand and tusk in left hand; to left, lion with captured bull Exergue: -/I//PKΔ Reference: RIC VI Carthage 26b #1 (Winner for CA's top coin of 2019): This might be a surprise for many, but I was so intrigued with @jamesicus work on London mint coinage, and my wins from AMCC 1, that I was always on the look for nice examples from London. This one was miss-attributed as Constantine, and it is an invasion follis that Constantius brought with him when he was re-taking Britannia for the Empire. You can read more about these coins here. I am fond of many aspects of this coin: the portrayals of Constantius and genius, the large flan and the large weight are some. It wins my gold award for top 10 of CA's 2019. Constantius I Chlorus AE Follis 294 - 296 A.D., Unknown Mint 11.15g, 28.5mm, 6H Obverse: FL VAL CONSTANTIVS NOB C, Head of Constantius Chlorus, laureate, right Reverse: GENIO POPV–LI ROMANI, Genius standing, facing left, head surmounted by a modius, naked except for chlamys over left shoulder, holding patera in right hand and cornucopia in left arm Exergue: -/-//- Reference: RIC VI Lugdunum 17a Thanks all for looking.
