Batch of 6 unknowns

#1: Islamic; probably early Ottoman. The only bit I can read is "zuriba" (struck), but the accompanying name of the place it was struck in is illegible.

#2: Extra cleaning might help; I can see text around at least one side, but not enough to read anything clearly. From what I can see of the letters, it looks ancient rather than mediaeval. The big crack probably ruins it as far as value is concerned.

#3: For coins like this where I don'y even know which way is supposed to be "up", I get the pic and try to slowly rotate it on screen until something recognisable appears. In this case, it hasn't helped... unless that large, A-shaped feature really is a letter "A".

#4: I want to say "Kushan", but only because I have a Kushan coin that's all glossy-black patinated like that, not because I can actually recognise anything.

#5: This one is the most identifiable of the lot. The hole is, sadly, not supposed to be there; holed coins are a fairly novel concept in the West, and coins aren't made deliberately like that until modern times. This one is/was Roman: on the obverse, one can read ...STANTI... in the emperor's title, and on the reverse "...ITVS" on the right; most probably a GLORIA EXERCITVS type.

Entering the legible text into the Wildwinds partial inscription search returns coins for Constantine the Great, Constantine II and Constantius II. The diameter is a fairly reliable indicator of date; the smaller the coin ,the later it dates from.

#6: Another Islamic; looks older than #1, based on the text style.

This thread shows that quality is very important to determine where a coin is comming from.

1st is an Indian coin of the islamic Moghul Empire. The pierced whole is 19th century.

2nd coin is Roman, faded away, 2nd or 3th century, struck in Roman Syria (Antiochia) according to the patina. Unable to identify the emperor.

3rd: something Byzantine, probably 20 nummi or K follis, perhaps emperor Justinianus I; in 538 he introduced the first portrait en face at the coin. These coins circulated far into the ninth century

4rd: the poorest of them all. Difficult to say. Something Greek, in between 400 BC and 200 AD.

5th Roman emperor Constantius, Siscia Mint, Gloria Exercitas

6th: Islamic coin, presumably from the Seldjoeks (ancestors of nowaday Turks, 6th century)
