Dies are made carefully from hubs, which are also made carefully. Coins are made carelessly from dies. If you go on YouTube and look up how coins are minted, you&#039;ll see it for yourself. Coins are minted rapidly, like machine-gun fire. Obviously, under high magnification, it would almost be a miracle if one could find a coin that came out perfect. Then consider the condition of the dies, after prolonged use. Do you see the deep crevases in your 1987-D? Those are from dies that are deteriorated, starting to fall apart. They&#039;re from dies that were hot and stressed from all the pounding into the planchets to make the coins. Dies don&#039;t last forever, either, just as coins don&#039;t. That&#039;s why, in the minting process, they&#039;re greased. Grease is slippery, the coins slip more when they&#039;re struck, and show it after they&#039;re struck. The grease also cakes into the recessed surfaces on the dies, clogs those surfaces, and that shows up on the coins.</p><p><br /></p><p>In a nutshell, if you&#039;re going to look for doubled dies, start by studying-up on them. This is what a doubled-die looks like. Note how the letters hold their shape, and aren&#039;t smashed, mangled or distorted. When it&#039;s from the dies, it will look like this, with the impressions just slightly offset. They&#039;ll be very close to the same height off the coin, too. Here you go...</p><p><br /></p><p>[ATTACH=full]835114[/ATTACH][/QUOTE]</p><p><br /></p>
