Artificial Patina - Four Identical Casts, Four Different Patinas101 viewsThis image demonstrates the talent of the forger in creating different patinas. The patina variation cannot hide that the coins are identical in centering, etc., because they are clones cast from the same mold. These types of forgeries are usually discovered quickly, but most often not until some have sold and the duplicates are discovered in sales records. Always buy from dealers that guarantee authenticity! Joe Sermarini

Artificial Patina - Fake Green Patina With Worn High Points Common on Sicilian Fakes127 viewsBronze dilitron, Calciati II p. 185, 80; SNG ANS 533 ff.; SNG Morcom 717; SNG Munchen 1159; SNG Lloyd 1456; BMC Sicily p. 189, 311; HGC 2 1439 (S), F, well centered, green patina, edge crack, light corrosion, Syracuse mint, 344 - 336 B.C.; obverse ZEYΣ EΛEYΘEPIOΣ, laureate head of Zeus Eleutherios left; reverse ΣYPAKOΣION, free horse prancing left; scarce
Reported by Din X who first suspected it due to the fake patina. This fake green patina is used by forgers who make cast fakes, most often of attractive larger Sicilian bronze coins. The patina is thin and worn on high points. This sometimes indicates a fake patina that should be carefully examined. This coin was confirmed fake by identical twins. Joe Sermarini

The patina first appears to be thick, but is actually thin and worn on high points. This sometimes indicates a fake patina that should be carefully examined.

Artificial Patina - Epoxy Filled Defects221 viewsThe areas surrounded by red are filled with epoxy material. The surface is painted. The coin is probably genuine and the epoxy filled deep pitting. The coin may be genuine but it is no longer in "collectible" condition.Ilya Prokopov

Artificial Patina - Different Periods, Same Patina226 viewsThe first coin is from the period 110-130 AD, the second coin is from 218-222 AD. But the patina is exactly the same! This is impossible. Fake sellers may have the same patina on many very different coins. Ilya Prokopov

Artificial Patinas - Multiple Copies of a Cast Fake Type - Note the Varieties of Patina712 viewsSince these are all modern casts, the patinas must all be fake. The patinas appear to be thick and rough but in fact they are very thin and the roughness is in the metal itself.
AE29: Septimius Severus
Reverse: KOIN PON NEOKAI METRO: ‘Neokaisareia, metropolis of the koinon of Pontus.’ Seated city goddess of Neokaisareia, surrounded by five standing city goddesses, three on the left and two on the right. A similar coin for Geta was in the Imhoof-Blumer collection, Griechische Munzen #55. Ih-B’s and the BMC’s interpretations are that the city goddesses represent the 6 cities of the Koinon of Pontus, an assumption that there were only 6 cities. Burrell thinks this interpretation is unlikely as there were probably many more than that and the coin is only a symbolic representation of the cities of the koinon to which Neokaisareia belonged.

Artificial Patina - "Jax" Patina572 viewsAE Follis
Constantinus II / IOVI CONSERVATORI
This patina may have been made with a commercial product called Jax. The patina is more blue than most (but not all) genuine patinas. As typical for fake patina, it is very thin and rubbed off the high points. Dirt has been applied to highlight the type and legends. Ilya Prokopov

Artificial Patina - Layered Artificial Patina455 viewsHere are the pictures from two coins with different chronology. The left is Roman provincial struck in 3rd c. AD, and right is Anonymous Bizantine follis. In both we see a thick layer of artificial patina. When examining the substrate on which the patina is applied I found that it is absolutely identical. I used a large optical zoom. Color is red-brown, almost cinnamon. The texture is slightly rough. The structure of the patina is also identical. The way the patina is flaked off and the type of metal beneath it is also identical. Shades of colors are close. I think these counterfeits are the product of the same workshop.Ilya Prokopov

Artificial Patina - Variations on the Same Fake Type416 viewsThe first two coins are cast and artificially patinated. They came to FORVM from two different consignors about the same time, one coin originating on UK ebay. The third image is CNG 158, lot 23. It looks extremely convincing and it is possibly the original from which the fakes were cast rather than a third copy.
The patina of the first specimen is identical to the patina we found on other cast fake sestertii, several of which are are already listed here.
Bronze AE 23, SNG Stancomb 310, SNG BM Black Sea -, VF, nice green patina, weight 10.371g, maximum diameter 23.7mm, die axis 0o, Kallatis? mint, obverse veiled bust of Demeter right, countermark of head of satyr right; reverse BASILEWS KANITOU, torch left and stalk of grain right
