This is a BU coin, my scanner doesn't show the luster, It appears very slightly sunken in around the BERTY in Liberty and around the state on the back. Is this a mint error and does it carry any premium towards the value?
It is a very common occurrence. It's called struck through grease. Some grease (lubricant) gets on the die or dies and what you see on your coin is the result of the grease being on the dies when the coin was struck. Have Fun, Bill
Thanks guys, I figured it wasn't much to go with, I have seen it before on coins and thought that maybe since this quarter was in very good condition that it might enhance it, but I think I will drop it back into circulation.
I once amassed an entire roll of 'struck thru grease' state quarters like this one that I auctioned off on Ebay. They sold for $10.25.
I don't know if it is struck through grease or not. Do the areas in question appear to be shiny or polished? If so, you are probably looking at a coin that was struck on a worn satin finish die. In 2005, the Mint began producing the Mint Sets with a satin finish, but they found that the life of the dies was much shorter. In order to prolong the usable life of the dies, they polished the areas of deterioration and used them for producing business strikes. You can find many of these coins with polished areas over much of the surfaces. Chris
I've heard this once before, but didn't know what to make of the explanation. I guess this is a good explanation for the super polished almost prooflike areas on so many coins. Something to ponder...
The satin finish die scenario does not fit. It is simply a coin that was struck through grease. many of us have seen it a thousand times before and that is a literal number.
