Hi, I've inherited an ancient roman coin from my grandfather when he passed away. I know for a fact that it is from the BC era and I know that for a fact.
What I don't know is what it's made of.
At first I thought it was bronze or brass or even maybe copper.
But I soon looked more closely at it and recognized a gold color on the sides of the coin,
This led me to suspect it was not bronze.
I took it in to a very reliable source and we did a basic acid test to see if it was gold,
It wasn't.
But the gentlemen informed me I shouldn't dismiss this as something that holds no more value then that of one made with brass or bronze or copper. He told me the metals composed in this coin were very very VERY soft, and that it just couldn't be copper or bronze:brAss.
He did instruct me to put it into my safety deposit box at the bank and to hold onto it until I get it identified.
He also told me that it felt like a typical gold coin, as experts know there metals, and continued to enrich me with knowledge about other precious metals such as, but by limited to,
Palladium, platinum, rhodium, and silver.
He stated that it looked and acted a lot like palladium or rhodium.
The thing is they didn't establish palladium until the 1800's and I believe platinum was in the 1700's. Idk about the rhodium but it's whatever.

Now this is where I'm bugged and need some help(for now). I will in fact get this thing checked by professionals some day soon, but I just don't understand why the coins so soft and has a feel and look of something that may be gold or something like that meanwhile I'm also being told from another source that they didn't use palladium or platinum back in the BC era.
Is this coin maybe not from the BC era and contains palladium?
I mean, the coins sides when rubbed very very lightly against a ruff porcelain plate it leaves gold looking residue. My friend told me gold and palladium and pretty similar in look and the way they react to certain testings, other then when palladium and gold are tested with an acid test, he palladium won't pass, only the gold will pass as gold. So is it possible this coin is palladium and I should have a test done for that maybe? I'm really broke and my next pay check is only enuff to cover my bills. So I'm wrapped for money as far as that goes. I livewith my wife and or daughter is with her grandparents because we aren't stable yet, as far as our home situation goes. We really want our daughter back and just can't afford a new place, even with the both of us working our bills just outweigh our income.. Between insurance cars food and living utilities and rent it's gone pretty much right away.
I really am praying that this turns out to be something worth around 40,000$.
That's what i was first told, and that was the lower end, the higher end would be 60,000$.
But that's when I thought it was made of gold. Now I don't even know what the metals in it are, although if it is bronze brass or copper, I am still looking at a few thousand atleast I know this, but one of my coin experts says it may just be some precious metal that is 5-6x more valuable then gold.
And others who want to buy this from me say they didn't use those metals other than gold and silver back in those days.


What's some opinions you guys? I really need some help and advice on what to do for now.
I have an idea, but just want what's best for me and my family and I would really like to maximizE the value and profit from this.
By the way this coin has been stored inside of a bank in a security safety deposit box for the past 25-30 years, quite possibly longer. My grandfather left it behind along with others to my father and I.
I'm posting a few close ups and using an iPhone six plus so it should be some good quality photos.
Let me know if you'd like to see it at a different angle. Also I'm getting it weighed today so I'll get back to u guys on that.
Anyways, here she is!

Antoninus Pius


Here's another site you may be able to find a match:

I'm no expert, but I think you have one too many zeroes in your estimates if it is authentic. If it's silver - lower still.

Agree with Charlie P. - Believe this is a bronze sestertius of Antoninus Pius 138-161 AD but get it identified by someone who deals in ancient Roman coins.

Pretty sure it's bronze

100% not palladium or rhodium. Both are platinum group metals discovered in 1803, are exceedingly rare, and are extremely difficult to work with. Both are white in color and whoever told you this piece might be palladium or rhodium was incorrect.

It is really soft , too soft to be bronze or brass or copper and it's not the coin in the photo��

Why is it so soft and has a feel of a precious metal I don't understand

It really appears to be the normal bronze, and the pitting is consistent with environmental damage to bronze, not precious metal. How did you determine the "softness" of the metal? Take it to someone knowledgeable in ancient coins, should be able to identify it pretty quickly.

Fishy.... 5 separate threads on this same coin. Seems a habit of multiple postings on same-same items. Must not like the answers received.

If not the same coin in photo, what gives here? That statement referenced throws a curve ball into everything posted.

Variant of Antoninus Pius, Billon Tetradrachm of Alexandria, Egypt. Dated Year 2. 138-139 - Billion is an alloy made of 60% copper and 40% silver. This would account for the softness and gold-like color. Don't assume it's rare just because someone cannot find an exact match on Google....get it to someone who specializes in ancient coins.

(Wikipedia) Billon coins from the Roman Empire, where progressive debasements of the Roman denarius and the Roman provincial tetradrachm in the 2nd century AD led to declining silver and increasing bronze content in these denominations of coins. Eventually, by the third quarter of the 2nd century AD, these coins were almost entirely bronze, with only a thin coating or even a wash of silver.

Deepseeker,
I agree; 5 separate threads on the same exact subject created by the OP has certainly confused me.
Perhaps the OP would consider alerting each thread that from now on only one thread (name it) should be used going forward.

I think the OP was referring to the photo that Charlie posted.

The coin is silver+bronze. Sorry for multiple post.. It's all the same coin, nothing is different. Same coin in every post
