<p>[QUOTE=&quot;physics-fan3.14, post: 3182929, member: 19165&quot;]I&#039;m not entirely sure what your example is intended to display. However, it illustrates very clearly the differences between the OP&#039;s fake error and this genuine error you show. Let me point out a few things: </p><p><br /></p><p>1. A dime is smaller than a cent. The coining chamber for a dime planchet is thus smaller than that for a cent planchet. A cent planchet CANNOT enter the dime&#039;s coining chamber, because it is too big. A dime planchet can enter a cent&#039;s coining chamber, because it is smaller. Thus, a cent struck on a dime planchet is possible - a dime struck on a cent planchet is not possible. This rule applies for any denomination you can imagine, and is a very easy method to instantly debunk a large range of so-called off-planchet strikes. </p><p><br /></p><p>For this reason, the cent/dime hybrid in the OP is impossible, but the one you show is quite possible. </p><p><br /></p><p>2.&nbsp; Notice in the OP, the cent is the primary image but the dime is the secondary image. This implies that the cent was struck, but the dime design was somehow inserted into this coin. On the error you posted, notice how the dime design is the underlying image. Most of the dime details are weak and appear like they were overstruck. The cent image is the primary image. In this case, the dime was likely struck first, and the cent was struck over the top of it. This fits with our observation in point 1. </p><p><br /></p><p>3. In the error you posted, both designs appear crisp and sharp. This is because both were struck at very high pressures by the mint (first one, and then another one on top of it). In the OP&#039;s coin, the Lincoln design appears sharp, but the Roosevelt design appears soft and indistinct. That&#039;s because the Roosevelt design was not struck at extremely high tonnage - it was hammered by hand, or inserted into a relatively low pressure vice. It imparted a shadow of the image, but not the full image. </p><p><br /></p><p>Given these points, there is a clear and logical explanation for how the error you posted could have been created, but none for the OP&#039;s coin. I suspect the error you posted was a coined dime that fell into one of the canvas carts that the mint uses to transport coins. The cart was emptied, but a coin was stuck in a crevice. This same cart was then used to transport cent planchets, and the struck dime fell out of the crevice. The struck dime was then able to be struck like any other coin, and made it&#039;s way out of the mint. </p><p><br /></p><p>There is no reasonable or logical explanation for how the OP&#039;s &quot;error&quot; could have been created, based on our knowledge of how the mint and minting process works. </p><p><br /></p><p>Thus, it&#039;s a fake.[/QUOTE]</p><p><br /></p>
