I started last year with some Alexandrian LRB and it seems that I start this year in the same vein. This is my new addition which is common enough but differs from my previous examples in that it has a "Laureate and rosette-diademed" rather than the "Pearl-diademed" bust of my previous examples. I know the obverse is a touch off-centre but it is a pleasing enough bust. Constans - AE2 Obv:- D N CONSTA-NS P F AVG, Laureate and rosette-diademed, draped, cuirassed bust left, globe in right hand. Rev:- FEL TEMP REPA-RATIO, Helmeted soldier, spear in left hand, advancing right, head left; with his right hand he leads a small bare-headed figure from a hut beneath a tree. The spear points downwards, between the soldier's legs. Minted in Alexandria, officina A; (/ALEA), A.D. 348-350 A.D. Reference:– RIC VIII Alexandria 61 My previous examples:-
If you look at the headgear on the emperor on my previous examples you will see that it is made up of small dots, which is a double string of pearls, tied behind the head, this is "pearl diademed". My new example has laurel leaves alternating with a ring, tied behind the bust again but with a rosette on the front, this is"laurel, rosette diademed". These are minor but noticable differences and are sufficinet to give them separate entries in RIC.
Martin, Wonderful details !!! Presently, I seem to have all 'varieties' (for one Emperor or another) except the hut series ....AH, another thing to do.... sigh...LOL
A question I have missed if it is common knowledge is what difference the diadem types made. I suspect something was being coded like the engraver ID but I have not seen it discussed beyond the fact that there are variations.
The Hut is the building that the barbarian is being dragged out of.... Here is a website that goes into this type in quite some depth. http://www.forumancientcoins.com/moonmoth/hut_analysis.html
Oki => click-on the link below to see "huts" https://www.google.ca/search?q=hut photos&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwi56b29ia_KAhXLKiYKHSCGCZIQsAQIGw&biw=1280&bih=935 ... ummm, there are zero-huts where I live!! (sorry, we do have a Pizza Hut)
The Celts typically lived in thatched round houses. There are various reconstructions of Celtic vilages around my area. Ventilation seems to have been a problem but it is thought that the smoke filtering through the thatch killed any bugs or vermin living in it.
All I can say is if you care in the least about these coins and have not read the link Martin provided, you made a mistake.
