Evidence of Pressing - Fake Flow Lines429 viewsThe style of this coin is completely wrong so we know it is a pressed fake. What is unusual about this example is the fake flow lines on the obverse. They really look very little like genuine flow lines. Joe Sermarini

Evidence of Pressing - Flat Fields403 viewsThe fields on this coin are much too even and flat, clearly indicating it was pressed. It was also made with dies with very odd and completely wrong style. Joe Sermarini

Evidence of Pressing - GENUINE COIN - Strike Flow Lines (example on a genuine coin)3425 viewsThis is a genuine coin. Many modern fakes are not hand struck. They are pressed using a hydraulic or screw press. These presses compress the planchet and force the metal to fill the die just like striking, however, the process is slower and usually done with an unheated planchet. Striking by hand (particularly silver and with heated flans) results in metal flow lines as seen on this coin inside the red circled areas. A coin struck with a new fresh unused die will not show flow lines. The lines are actually worn into the die by flowing metal. The more worn the dies, the larger the flow lines you might expect to see. The dies used to strike this coin still have good detail but the flow lines are already fairly strong. This is fairly typical for the time period and is probably related to mint techniques of the era. Many genuine coins do not have flow lines as obvious as this coin, however, this coin is a good example for study. These lines are usually missing on pressed fakes and are often missing or reduced on cast fakes. Joe Sermarini

Evidence of Pressing - Lacking the Imperfections of Hand Striking2702 viewsMany modern forgeries are not hand struck, they are machine pressed. Pressed coins normally have strangely flat fields, a lack of flow lines, no doubling, no slippage, uniform strike (no flat areas), and uniform thickness. Often these coins are also very well centered. Slavey coins are pressed (to see more pressed coins use the search function and search for Slavey).

Evidence of Pressing - Near Perfect Strike308 viewsThis coin has near perfect centering and a perfectly even bold strike. Genuine coins are rarely struck this well and any coin struck this well must be examined very carefully before being accepted as genuine. This coin is fake. Joe Sermarini

Evidence of Pressing - Steps on Rims392 viewsOn the reverse rim on the right side it appears the mechanical press did not move in one smooth motion but rather in steps. Perhaps the pressure was applied with a hand pumped hydraulic jack.Joe Sermarini
