John Anthony answered your question. Constantinius II coins are ca. A.D. 337-361. It appears to be a genuine Roman bronze coin.
I beg to differ. All coins are worth something especially when there is enough to identify it like this one. It's not rare nor is it worth much, but it is worth a couple of dollars.
Just a little more information for the OP- On the obverse you can read CONSTAN to the left side of the head. The name continues on the right side of the head TIUS. The reverse depicts a Roman soldier standing on the right (facing left) and he is spearing a fallen enemy that is located on the lower left. This reverse type is called (fallen horseman) & you can see some decent detail in your fallen horseman. I cannot read the string of 5 letters at the bottom of your reverse design. A couple of the letters at the bottom of the reverse design would indicate where the coin was minted. Others here could probably tell you much more about the coin. Those letters below the reverse design are referred to as being "in exergue". The coin is 1,650 to 1,675 years old. There is a lot of information you can tell people about that little piece of bronze.
I think I see SIS, which would make it Siscia mint, but it's so worn that it could just be my imagination.
Personally, I hope you don't plan on selling it (you will get little bucks for it anyway). It's has way more historical value. Think about it, you have a 1700 year old ancient artifact in your hands, from one of the most famous empires. How many people around you can say the same? Plus there is so much cool history behind ancient coins, and this one is no exception.
Coincidentally, the word of the day from DrGoodWord today was PAREIDOLIA Pronunciation: pær-ai-DO-lee-ê Part of Speech: Noun, mass Meaning: The false or mistaken recognition of images in a random pattern, such as seeing images in the shapes of clouds or features of the human face on the moon.
the coin is worthless or close to worthless. i know that now. i paid $15.00 for the coin. this is the first ancient coin that i have ever bought. i don't think that i want to buy anymore ancient coins. they are not worth much.
This particular coin may not be worth much, but we can all show you coins that none of us can afford (unless you are a mega millionaire). But if you buy a coin for $15 w/o knowing it's potential value, then you get what's coming. In this case perhaps a $5 coin. Stick around, you can learn something about Ancients and their values. Besides value is only one minor parameter. Historical significance is a much more major parameter.
Hello Coins776, Don't give up on interesting ancient coins too quickly. Check-out this ancient coin recently posted at CoinTalk. It is sweet. http://www.cointalk.com/threads/ancients-a-couple-of-nude-dudes-a-horse-and-a-dolphin-huh.236453/
I'd equate this to the realization that some Lincoln cents are worth only $.01. I am amazed at how some US collectors can see a value difference between a cent with or without a certain mintmark but believe any ancient coin to be the same despite grade, type or denomination. They only made ancient coins for a bit over a thousand years so we should expect them all to be clones.
Guys, coins776 is just somebody's trolling account. If you visit other parts of the forum, you'll know. There's nothing here to be taken seriously.
