My cousin have coin or we think its coin. If someone can give us some information about this. Thank you.
you might want to post this in the ancients section. I'm still new enough with ancients that I can't ID it, but it sure looks like you might get more feedback over there...
just realised too, you might need to post a pic of the reverse of the coin to help the experts ID it.
Welcome to CoinTalk. I will report your post and ask to have it moved to the ancients forum. They will need a pic of the back, and if possible diameter in mm and weight in grams.
I believe this "MAY" be your guy: ANTONIUS PIUS http://www.wildwinds.com/coins/ric/antoninus_pius/i.html I'm fairly new to ancients but without a picture of the reverse, it's the best I can do.
It IS Antoninus Pius (138-161 A.D.) However I cannot tell if it is a sestertius (orichalcum) or as (copper).
I'll guess it is an as. Sestertii (first below) of this period tend to have a sharper, more squared off edge while asses (second below) are more smoothly rounded over. Those who have both are asked to check my theory here and report if our coins agree. I suspect the blank flans were prepared in a different manner but I have no idea why.
That, plus the fact that asses were more common back then (seems they still are today, but that's another thread) means that statistically, your coin is more likely to be an as. When all else fails, go with the odds.
