Gold Die Set-Up US $20


TMgavel.gifDie Set-Up Gold Coin at Stack’s

On March 26th Stack’s will be offering a very interesting Liberty Twenty Dollar gold piece for sale in their Dominic Gaziano & Papyrus Way auction. Some might catagorize this coin as an error, but it is actually a die trial struck while mint workers would have been in the process of setting up the dies for production.

$20 rev.jpgOnce the dies are secured in the coining press, workers will strike a coin. We call these coins die trials. Sometimes a die trial is struck in a softer metal than the production coin. This is often done at an early stage, well before production. Sometimes a square oversized piece of lead may be used. These lead pieces are called splashes. During the process of making the various elements of a coins desing into the die, some mints used to make progressive die trials to see how the work was coming along. These pieces only display a portion of the final coins desing.

This particular coin in Stack’s upcoming sale is a set-up die trial. In this case, a die is all ready and production is to begin very soon. The mint workers begin by securing the dies into the coining press. At this point the dies are placed rather far apart, so that they will not clash and be damaged. Then a coin is struck using a planchet of the official metal. As you can see by the softness of the Stack’s set-up trial the dies were$20 obv.jpg too far apart, so the mint workers would have adjusted them closer together and this process would have continued until the ejected coin was fully struck up and all details were clearly visable.

Set-up die trails are normally not allowed to leave the premisses of the mint. Most, I believe, are destroyed after the die set-up process is complete.

To find one available for sale in the market is rather rare, so this Stack’s lot is a great opportunity for any U.S. Gold collector to add something unique to their collection.
