I got this 1989 mint set with the Philadelphia quarter struck through. Please let me know if you have seen other errors still inside the mint packaging & post pictures if you can. Do you think that the value is bumped-up because it is still in the original packaging? Very best regards, collect89
That's a greased filled die minor error and the price will not be bumped up because its in the mint pakage, and those errors don't bring much of a premium anyway even if you sold it alone the quarter sorry Jazzcoins Joe:whistle:
It appears to be from a grease covered Die but with some damage on the Reverse as well, I am not totally certain that this was the cause! I will leave this one to Mike Diamond. A better assessment could be made with close-up pictures of the entire Obverse and Reverse of the Quarter. Yes, I have and I am sure many others here on C.T. have seen these and many other types of errors on coins in Mint Sets as well as some Proof Sets! Frank
This is the best I can do today shooting the photo through the mint plastic. Very best regards, collect89
It really appears that there was a lot more going on during the striking process when the coin was minted, than just grease on the Dies but what I am not sure! Possibly the Obverse problems are from a late stage Capped Die strike. From the looks of the coin, one would think that a Mint employee took a well circulated coin out of their pocket and sealed it in the plastic. Frank
Just grease on the die. It was struck through a heavy layer that may have had some particles of debris mixed in and that's why the obverse looks the way it does. It wouldn't add a ton to the price of the set but a few dollars extra wouldn't be unreasonable only because of the severity of the filled die. Thanks, Bill
