Utah States Quarter – Struck through Grease?
Saturday, April 18th, 2009While I was looking through a roll of States quarter dollars I found one that looks unusual. The “UT” of Utah is almost missing and the 2007 date is very faint, as well as the motto below it. On the obverse the “UNI” in United States is also very faint. So, the question is…..Would this be considered and error coin or have any value?
There are a few possible explanations that would fit this description.
1)The coin was struck through a layer of grease and the details as described were not fully struck up as a result.
2) The coin was actually weakly struck and the pressure applied during the strike was not up to the necessary amount needed for a coin to be fully struck.
The most common explanation is the struck through grease scenario. If you see patches of irregular surfaces around the weakly struck areas then this would be the likely cause.
Either one would technically be considered an error but a coin struck by a grease filled die is not so unusual and a premium would be minimal.
A weak strike is less common and would be worth a few dollars depending on how weak the entire strike was.
