Coin and Paper Money Collecting/1991 dime missing "us" in pluribus


I have a 1991 dime missing the "us" in pluribus. The first U in unum is barely noticeable. It looks like it was a weak stamping. Just wanted to know if there are many like this and what your professional opinion is.
   Thank You

Hello Emily,

Its difficult to give you a specific answer without seeing this coin. It sounds like you have a "struck through grease" error. This occurs when some foreign material, lubricating grease typically gets onto the planchet or on the die. This grease prevents the die from making a complete impressions on the planchet resulting in missing features like you observed.

If you send a clear photo I can confirm this.
