Clearer and larger pictures would help for sure, but I'm leaning toward fake. These are heavily faked, and tourist replicas are common. The surfaces don't look right to me.
NOTE TO ALL POSTERS: Coin authentication is no longer a matter of naked eye or 5X magnification. Many coins now require at least a minute using a stereo microscope at powers near 15-20X! Asking even a professional numismatist or advanced collector to answer a question of authenticity from a photo is difficult at best. Asking them to do the same when they cannot see a highly magnified image of a coin's surface is fruitless. Especially with ancients. PS Welcome to coin talk, this is not directed especially to you as EVERYBODY does it.
I agree with Insider when it comes to authentication but will point out that some fakes can be declared from ten paces with one eye closed. Regulars here will start to recognize certain 'things' that pretend to be ancient coins and are posted here by people who recently have been exposed to coins in general or ancients and are imagining they are beneficiary of the deal of the century. There are experts who are fooled by .01% of fakes. They tend to work for big dealers or authentication services. There are those who would be better served by flipping a coin to determine the answer since their hopes for the best will more often turn out bad than not. It is OK if you ask our opinion on a coin but you will have to realize that relatively few of us are in the 90+% accurate group and are not able to apply Insider's stereo microscope to your cell phone photos. Ask away but understand when the answer you get is rarely as 100% positive as you hoped.
I might also point out that there are some coins that actually look better under a microscope than they do at arm's length. It is hard to evaluate some things when over magnified. We do what we can.
I appreciate the difficulties but I've added a few more images that may help, can anyone recommend a reliable expert North of England would be best.
I am a little further North. You could google "coins manchester uk" and see if there are any in your area. If you are interested in coins, there are coin shows, monthly, in the York and Birmingham areas. I haven't been (due to a fall) so I can't say how well ancients are represented. It depends how far you are prepared to travel.
I have avoided purchasing one of these because most of the ones I've see look suspicious. I'm not even close to being an expert however.
From the larger photos...still not enough magnification...I'm 98% counterfeit. Too many perfectly rounded blobs on the surfaces. Little metal flow.
Thanks for all your replies, there is a dealer in Blackpool who is interested and waiting a response. If not I can travel within U.K as far as I need. The coins were dug up a number of years ago by my late grandfather, that's why I thought they could be genuine, the area although not specific does have Roman history alothough I know most places in U.K were visited at some point by the Romans. If they are fake, why would they be buried ?
I can not say anything about your coins as I do not collect Judaen, only point to an instance relating to your question. This is more for general awareness of those not familiar with the lengths forgers can sometimes go through. Excerpt taken from http://snible.org/coins/fakes/dodson.html
