The LCS had it labeled as an 1878 Philadelphia. I flipped it over and saw the mint mark. I told the guy behind the counter that it was a Carson City and handed it back so he could see it.
He said, "yes it is". I asked how much it was since I thought it'd be more. He replied, "it's the price on the holder"...I looked the code up and it was $10.
I do a lot of business with that LCS and wouldn't have felt right if I hadn't mentioned it.
I was thinking AG-3 as well.
