I have no idea what this coin is and need assistance classifying it. Also, the detail actually appears to be fine to very fine on the coin even though the crust or film on it obscures the devices somewhat. Is there any way to remove this film of material w/o destroying the patina or value of the coin?   |

After posting this I forgot to mention that this coin is fairly bent. It's probably the primary reason why the detail has remained so nice. Anyhow, the lighting angle obviously changed when I laid it inclined on one of those big erasers. The lettering and all devices should be much easier to distinguish now. It looks like it says AMTAV on top.  |

Top lettering is: ANT AVG - short for Antony Augustus
Bottom lettering is: VIR RPC - not sure what that's short for. Regardless it was minted in 32-1 BC by a military mint traveling under Marc Antony.

I'm trying to figure out what the deposit is. These are silver coins and I'm wondering is the deposit is horn silver or the coin is a fouree.

the lettering on the obverse is : Ant Au III vir RPC : Antonius Augustus triumvir rei publicae constituendae : Marcus Antonius , one of the three man to re-etablish the republiv ( with Octavianus and Lepidus) . These coins are supposed to be minted in Patrae Greece)by a mobile mint and the quality and purity of the silver was not so good as normal .albert

Where does one find the value of this type of coin?

They are very common coins, but also very valuable (compared to other similarly common Republican denarii), especially if they have full legends.
If it is not a fouree, you should be able to clean it up, which will tremendously help the eye appeal and therefore value if you were to sell it. Depending on how that turns out, a no reserve auction would likely land somewhere in the $50-75 zone.

I typically use xylene(xylol) to remove crud off of old copper.
Would this same chemical be acceptable to remove the unknown residue from this alleged silver coin w/o causing any deleterious effects on the patina ?

Marcus Antonius was never "Augustus". The "Aug" refers to his duties as Augur.

Yes you are correct. Since I only collect Imperials it's hard to think of AVG as anything but Augustus.

I'm guessing that the "crud" you are removing from copper is hydrocarbon based. The deposit on the silver coin looks to me more like a lime deposit. I don't know how xylol reacts with silver but I would not expect to see much. You might test it with a small amount on a cotton swab on a small area (spot) to see what it does to the silver before plunging it in. If you do have a lime compound on the coin, try to flake off a small amount and test it with some "Lime Away" in a rag to see if that has any effect on it. If so, then test the silver for reactance as before. Edited by lrbguy

Xylene would certainly help to remove Renwax or similar.
Sometimes, museums apply Renwax to help preserve coins. (More commonly bronze coins).
Worth a try.
IF it is a modern fake, (and I will not comment about that), it may have a lead core.
Try bending it slightly between your fingers.
I was once sold a fake, honestly thought to be genuine by the dealer. That particular coin was found out to have a lead core.
