Here is a replica 1944 Tombac nickel. The camera and sunlight worked together just right to show the porosity of this replica. You can see how the letters and design all have a micro-bumpy surface to them. This is an easy way to tell most counterfeits. Be warned though that this picture may be deceiving! Because when you are holding this little item in hand, you could swear it is real! The angle of the sun for this pic was just right. Even in direct sunlight you probably will need a magnifying glass to detect any of the newest Chinese replicas.    |

Thanks for the helpful pics Earle.
is the micro-bumpy surface thing true for most counterfeit coins?

I read before that this is a common thing. I know all of the Chinese fakes I have (got them for the sake of learning how to tell fakes of various types) all have this porosity to them (except one - a 1799 dollar).
I am glad to share these things. I figure the more we know, the better prepared we all can be.

Thanks Earle42 for sharing these things. Does anyone have an idea who is importing and dumping them on our market?

These were made in China by a guy who used to sell them on ebay (until they stopped him). I do not know how prevalent they are, but since they were on ebay for awhile, there may be quite a few. Actually, with a coin like this one that most of us would never get anyway, I do not mind a copy. But unfortunately he did not only make the novelty items like 1804 dollars etc. I believe some of his copies are being sold on ebay and other online auction sights. Last fall I spotted one on iBid and could recognize it b/c I have a copy of the 1799 dollars he made and the same error was on the one in the auction that was on my copy.

BTW - the error on the 1799 dollar was that he confused the back of one of the known dies with the front of another. otherwise this thing is almost perfect. The only other thing I can find is the serifs on some of the letters are a little different.

Fakes are quite often die struck. In this case a porous surface is usually not found.
For a fake to me made, information has to come from an original coin. That can be done by laser optic scanning and the information stored digitally. A die can be cut from this information using a spark erosion die cutting process. The die is cleaned up by hand under a microscope before being installed in a coining press.
Chinese fakes are often made this way.
Common (but genuine) U.S. gold and silver coins have been used as donor planchets, so that the fake is of the correct metal and weight. In this case the donor coin, which is used as the planchet, is over struck as many times as necessary to completely obliterate the original donor coin information. Obviously, you would only fake very high value coins with this technique to justify the expense.
Even so, a die cut fake can still be picked, because the transferred information onto the fake is not as clear as the original. Experience IS necessary to know what to look for, the eye has to be trained.

Most Chinese fakes are die-struck, not cast, so porosity would not be a clue for detecting them.

That coin certainly looks like a corroded 5 cent piece that was found in the ground. Strangely with almost no contacts on it,...but corroded...  Why would anyone do such a poor job on it,.."as a fake"...? Anything other than the rare tombac variety would hardly command any money if looking like that one. That 5 cent piece looks like a very poor and undesirable coin. Wouldn't any collector consider that one just a corroded coin and of no value in that condition. 007 ...Could you post "large clear pics" of your set of the 42, 43, 44, and 45 ...? . . . . .
