Coin and Paper Money Collecting/Mis stamped quarter. Date unknown


mis stamped quarter on right
mis stamped quarter on  
I found this going through some change the other day.  It looks like it wasn't stamped hard enough.  In the picture, it is the one on the right, the left is a normal quarter.  Are these rare?  What are they worth?


Photo is poor quality, too hard to establish what you have. Two possibilities exist for real errors of this type. Filled or greased die and die adjustment strike. The latter is scarcer.

A real error coin like yours, if a die adjustment strike, would likely retail for approximately $50 to $125. This happens during te start up or shut down of the press, where the full pressure used to strike the coin, is not used. The result is a coin lacking the design, and lettering in the center of the coin. An altered coin would have no added numismatic value. Someone may have put the coin on a buffing wheel and ground it down, making it thin.

Sometimes people try and fool you into thinking you have a real error coin. Here are some examples of coins either being altered or damaged.

A greased die is the result of dirt, grim, and machine oil getting on the surface of the die as the coins are struck. This type of error would be repetitive, and hundreds to thousands could be struck until the operator catches the error and/or the die surface is wiped clean of the "gunk".

As far as value, it would depend primarily on the condition of the coin and amount of die surface that is filled. Circulated filled dies trade for about $3 to $5. Uncirculated filled dies can bring from $10 to $25.

Check ebay listing under US coins in the error category to see if coins like yours are listed. You may also want to check out these links on error coin values:

Remember, should you choose to sell your coin, get at least two estimates from professional coin dealers (PNG). I've listed a link for you to find them in your area.

Dealers normally pay between 50% to 60% of retail for items they want.
