Walking Back In Time From Rome

Thank you Spence , interesting coin . What me wonders is the pronounced dot , these coins have usualy a dot ( like the Ptolemaic) on the same place but not so pronounced .
For this last ( in fact first) decade of the 2th century , 200-191 , I have a Greek drachm . For the next decades , it will be Roman to end in beauty .
AR drachm , Rhodes , 15 mm , 2.88 gr , 11 h
obv : radiate head of Helios right
rev : magistrate's name :ΑΡΙΣΤΟΒΟΥΛΟΣ I quadratum incusum, rose with bud , P - O across fields
mint : Caria , Rhodos , 198 - 187
ref : Jenkins,Gruppe A,10 . albert

Following the Rhodes coin I was looking at mine with its enormous date range and wondering why the presence of a magistrate doesn't pin it down.



Was there more than one Gorgos or am I safe to assume that 205-190 BC is the date range (an assumption based on the date range of another Rhodes coin seen with the same magistrates name)

For the first decade of the third century : 210-201 .
AR denarius serratus .
Obv : Helmeted head of Roma right , mark of value X to left
Rev : The ΔΙΟΣ ΚΟΥΡΟΙ on horses rearing right , each holding a spear , two stars above , wheel below
Ref : Cr 79/1 , minted 209-208 ;
Mint : uncertain , maybe Sicily , 19 mm , 4.2 gr , 3 h
Number of dies : obv:40 , rev : 50 . albert

Roman Republic Semis Saturn Right / Prow Crawford 56/3 211-206 BC 28mm 16.3g

Here is a Greek Drachm of Ptolemy IV. The lambda between the eagle's wings signifies year 11 of Philopator's reign, or 211 BC. I have it attributed as SNG COP 222 and Svoronus 1167.

My last Roman coin for the decade 230-221 .
AR quadrigatus , didrachm :
obv :Laureate janiform head of the Dioscuri .
rev : Jupiter in quadriga right,driven by Victoria . Jupiter holds sceptre in left hand and hurls thunderbolt with right hand, in exergue : ROMA on tablet .
Ref : Cr29/3 :
Mint : uncertain , 225-214 BC , 18 mm , 5.6 gr , 3 h .
Crawford has suggested that the janiform heads represent the Dioscuri , since Janus is usually a mature and bearded figure .albert

Yes I think January's coin is in the good decade of 220-211 . IMO a decade BC begins in the year 10 , 20 .... , the last decade before the bird of Christ begins in the year 10 and ends in the year 1 , because there is no year 0 .After the bird , it begins in the year 1 to 10 , like the third milenniun began in 2001 and not 2000 .
THe next decade will begin in 230 to 221 BC and there is a real problem with Roman coins , there are very scarce and for the period 250/225 I think there are no coins .
For Greek coins , I think it is better to work with periods of at least 25 years and still then,we will have problems .Maybe working with half centuries ( 50 years) over 3 or 4 days ? albert

It's tricky we are wanting a coin that dates 230-221 BC period. The closest I have is a coin minted 250-175 BC

Has anyone anything that starts in the correct decade? (even if it runs on for a while too long) and do many coins exist that start in the correct decade?
