Any help identifying this coin is very much appreciated, I have searched the web for several hours and cannot find this particular coin.

I believe it weighs about 4.2 grams

This is a modern fake. Here is an example struck as a denarius from the same modern dies. Published by I. Prokopov, Sofia 2003, no.148

It is though with the struck fakes. That second example shown by maridvnvm has a bad style in the reverse but I think would not raise suspicion for other reasons.
I do not think it was the same die used in the first coin. Another one one from the same group now disguising bad style as wear?

OP's coin waaay too light, - it should weigh a bit over 7 grams

My guess is that is composed of gold plated base metal.
XRF rather useless in this case, - it only analyses the purity of metals in the surface layer.

------------------------------------------------------------------------------------------------------------------------------------

One of the easiest ways to pick a suspect fake style is to look at the face details.

We all have a powerful recognition ability to compare minor face details, and so comparing the style in this case
is to have a look at the whole range of face images that are found on
Vcoins - Caracalla as Caesar,
and
Google Images - Denarius Caracalla as Caesar.

This exercise is worth doing for all fans of ancient coins, here in the CCF just to improve your fake detection skills.

The OP coin and the fakes that I illustrate are ALL derived from the same fake dies. Please show the the differences in the die that indicate that they are different.

Thank you all for your welcomes, valuable feedback and insights.

I put the coin under a high powered microscope and took photos and then relayed them to an appraiser.

His opinion concurs with the consensus here.

It is a counterfeit/replica that does not correspond to an actual coin. It also shows base metal under gold plating.

Maridvnvm thank you for sharing Ilya Prokopov's works with me. I have since downloaded all public domain material about these modern counterfeits and the Bulgarian studios.

At the time of purchasing the antoninus pius, I also bought three other coins from the same ebay seller and the appraiser came to the same conclusion regarding those. All of the designs are off in his opinion.

Tough lesson but gives me an education at the same time.

I look forward to spending some more time on this forum and sharing some of my other coins both U.S. and World in the future.

Best,

David

I would generally advise staying away from ebay for ancient coins, especially for newbies. There are simply far too many counterfeit, illegally looted, or mis-identified coins out there.

I was not doubting the fakeness of the die. Or that it was from the same forgers. But it looked struck with a worn down die, softer.

Not I read it was gold plated, that was what caused the softness.

My guess is that the base metal is high zinc fresh yellow brass.
For a short time, a scratch that would breach a 10 or 20 micron gold plating would not be too obvious.
As it turns out, this 'coin' does not appear to have any scratches that deep.

This 'coin' is worthy of inclusion in a 'black' collection of fake coins for self education purposes.

If it was in my 'black' collection, it would have been in a 2x2, and labelled:
"Fake, brass base metal core, gold plated 4.2 grams - (under weight)". From where I had obtained it, would have also been noted.
