I was poking around on the Forum discussion boards and there was a post about a Trajan As which the poster suspected was fake. This was confirmed by others. I think it would be valuable for me (and others perhaps) to post the coin here, and have more knowledgeable members discuss the counterfeit signs.  The posters talk about a casting rim on the coin. What exactly does this mean, and is it visible from this photo? Also, they mention the hammered edge where the sprue was cut off after the pouring of the metal. Is that the extrusion at the top of the coin, c. 11 O clock? Just looking at the picture myself, the coin seems to be quite pitted? Are these casting bubbles? Thanks. PS: Perhaps it might be an idea to have a thread where people can post examples of fake coins, and members could discuss the obvious signs of counterfeiting? Just an idea!

I have not seen the discussion on this coin but I don't see this as obvious either way. The coin has a lot of damage that could be from being a field find roughly cleaned of corrosion. I could be a fake. It is the sort of coin I would not buy because it is ugly or because it was possibly fake. A lot of the discussions on the fakes at Forvm become witch hunts with people yelling 'Fake' when they don't really know what they are seeing. A good example of this is a denarius of Vitellius recently moved back to the Roman Forvm after being moved from there to the Fake section based on differing opinions. In the end, the powers that be decided that the opinion of a very respected dealer outweighed the opinions of lesser ones but it is a sign that not all coin photos will allow 100% accurate classification. Remember that experts that slab ancients do not guarantee their opinions like they do with modern US coins. Even with coin in hand and all the tools we have, there will be some differences of opinions and some flat out mistakes.

I thought about suggesting such a thread with comparisons of real and fake coins but then I thought maybe it is a bad ssuggestion to educate the fruadsters how to do a better job.
I believe a casting ring maybe what they call the line caused where the rubbers where cut apart to make the wax models from which they cast. The simplest way to describle that is a line exists where two halfs of a mould fit together.
It looks like a sprue would have been attached at the 9 o'clock on the coin you show (there is a mark at 11 too so not 100%)
Casting bubbles appear as porosity, the roughness of this coin is not that; just they didn't buff the fields of the coin dead flat maybe because the details are in their way. (Obviously a minted coin doesn't need to be cleaned up in the same way a casting does)
Also it is impossible to cast metal to below certain thicknesses and that means crisp edges and fine details can't be created by a casting to the same standard as a strike.
I am no expert on fake coins and wear and bad quality can be confused, I guess there is no substitute for handling and dealing with the real thing and the fake and building experience... there is no substitute for experience.

I think the thing they think is the spue is the feature near the edge at 9 o'clock. Like Doug I couldn't really call this one from a picture alone. I've seen and handled many coins of a similar wear before - even to the point they look cast - it's just the way they have been weathered in the ground. There's something a little soft about the details on the obverse of this coin I just don't like and makes me suspicious but not enough to just outright condem it from a picture alone.
Either way I wouldn't buy it as you can pick up much nicer examples easily.

The other images are REALLY relevant here as they illustrate the edge with a blatant casting seam including filing on the edge.

I'm terrible at picking out fakes, but the softness of this coin, both obverse and reverse, would make me pause. As steve6x once quoted from the movie Ronin Quote: Whenever there is doubt, there is no doubt .

I agree with Doug, this coin is a bit worse for wear and it's appearance can be due to that. I can not dismisses it as a fake without having it on hand to examine.

Yes. This thread was a set up and I bit. The photos of the obverse and reverse were presented but why were we not shown the edge photos that make it 100% obvious that the coin is a cast fake? Could the coin be an ancient fake? Possibly, but the edge seam all around the coin with file marks where the sprue was removed shows that it was not an official, struck coin. However, any signs of it being ancient have been removed by harsh cleaning so there is no reason to believe the coin is anything other than a modern copy. I should have gone to see the Forvm post before making the first comment but I will repeat that I can not accept this question as having been asked in good faith when it was decided to shown the photos shown and hide the fact that there were edge shots and that those edge shots were what was discussed condemning the coin. On my page on fakes: http://www.forumancientcoins.com/do...th/fake.htmlI show a cast fake of a denarius of Septimius Severus including an sdge view that is no where near as good as the one on this Trajan. My page dates back to when I was trying to make my pages faster loading for people with dial up modems. I really need to redo that page instead of wasting my time here!

Doug Smith - Is there a good write-up on what constitues a silver foil coin fake or what process was used to make silver foil ancient fakes?

The OP coin did not show the edges, if it did than I would agree 100% that it's a fake.

I think you're being a tad hasty in casting me (no pun intended) in this rather negative light. I apologise for overlooking the other pictures, but that's all it was- a simple error. And easily explained too. I didn't realise that one had to be logged in to see images in the Forum discussion boards. As I wasn't logged in, I saw nothing to indicate that there were other, more incriminating pictures. When I popped back into this thread just now, I immdiately retrieved my password from Forum (having forgotten it), logged in, and saw the other pictures. That's it. There was no attempt to pull the wool over anyone's eyes, or pull a stroke. I'm newat collecting ancients, and I value the opinions of others here, especially yourself, so the last thing I would wish to do is annoy people by acting the dick. Apologies for the omission, but hand on heart it wasn't intentional. On the plus side though, I know now what a casting rim looks like, and I also know that one needs to be logged into Forum to see their pictures!! Not bad for a cock-up of a thread!!

Don't worry about it einhard. It was an understandable error. No one was trying set anyone up. Keep asking questions. It's the best way to learn.
