jun123, I have the same 1753 Pillar now posted in another thread of this forum. https://goccf.com/t/133160&whichpage=2I am quite confident mine is genuine. What is the diameter of your coin? About yours, I think the 4-petal flowers on both sides of your coin is crude and not consistent. Did you buy your coins from a reputable or reliable seller. Henry |

Both coins are suspicious - the first looks like a cast copy - the second looks like it was struck but definitely from transfer dies. Appearances can be deceiving in pictures - they should be studied under a 30x to 100x binocular scope - should have SG run and possibly XRF for 100% certainty. There are based on my estimates about 3 fakes for every 2 real coins in the market place and ebay is FAR worse more like 4 to 1. |

Thank you guys. I bought these from ebay and the seller is tercio_galico from spain. The SG of the 1755 is 8.7. and the 1753 is 10. What is the correct SG for these coins? |

I was using a filtered water to measure the SG. Does this affect the accuracy of the measurement? I measured again the 1755 and it is 9.64.

swamperbob is my teacher of S.G. measurement. But as a student of this field, I dare to say both of your S.G. are too low to support your coins are of correct fineness of silver. I prefer distilled water from filtered water. What kinds of filter, resin or filter paper to be used in the filtration? They give very different effect. The S.G. of my 1753MoMF pillar is 10.274.

The density of the water is only marginally effected by the difference between distilled and filtered water by most accounts. The need for the 4th decimal of accuracy is for discriminating below 0.1 SG. Water type - the addition or lack of a water thinner like detergent - pre-boiling to remove air and the room temp are not overly critical at the 3rd decimal level which translates to SG accuracy of 0.1.
The nice thing about SG is that it is very discriminating. Any coin under 10.15 is automatically a FAKE in my opinion. It is also so badly debased that it should be noted at the point of sale. The typical silver fake in my experience tests at about 9.8 to 10.1. Typically 700 fine is the lower limit for a Numismatic type silver counterfeit. There are cruder fakes "casts" that hit an average of 9.5 to 9.8 which were extremely common in the market place a couple years ago but the supply dried up as fast as it showed up. These were usually found with a ragged transition between the faces and the edge. They came from China. The better silver fakes often come from Spain and/or eastern Europe and are specifically targeting numismatists of a MODERATE skill level.
If you were testing above 10.25 then I would advise following EXACTING standards for the water and retesting to the 4th decimal. But when you are below 10 that is WAY THE HECK OFF. I typically cull out the bad fakes with a 3 decimal tap water test using a 2% accuracy scale and only drag out the better apparatus on a "better" grade of fake.
Sorry to say it, but I think those readings seal the deal so to speak. The two coins are $30-35 counterfeits.

tercio_galico is a known counterfeit seller ... sorry for that :/ His real name is JUAN MELGAR - he has more than one account, and list genuine coins (some he don't even own, I've seen pictures from other serious sellers) with his crapy fakes. He is particularly specialized in counterstamps ... Check out the datas on our "regular fake seller" list : https://www.facebook.com/groups/mon...07011379478/Edited by MathieuMa

These are really poor, not scary copies. find a local expert. Ponterios gave thumbs up to everything except coins I bought as copies.

tercio_galico gave you that name ? hum, that's strange ... He is in malaga, and I'm 100% sure I recognized his finger tips on his auction pictures (yep, it went that far :P) Nice story, as if monasteries where giving out fake chinese coins ... and roman ones as well ... ( http://www.ebay.es/csc/tercio_galic...H_Complete=1 ) Anyway, as long as you get your money back ... |
