So a few years ago I was buying bags of Wheat cents from one of my LCS. I discovered this one cent and I believe I hit the jackpot with this beauty. Of course, this will be determined by you fellow collectors with more experience then I have. I didn't spot it right away, however, after doing some research on coppercoins.com I found it too match the 1958-D-1MM-021 which is a D/D/D/D/D W, NW & SW & SW described as "One of the most peculiar repunched mintmarks in the series, this variety shows an extra lower horizontal to the west, an extra lower serif to the northwest, and two completely separated punchings in the vest area" (coppercoins.com). I imaged my coin to the best that I could and paired them up with the MDS and LDS images from coppercoins.com and I hope these images work for you to determine if I am correct or if I am just seeing things. I would also appreciate an estimated grade for this coin. Thank you for looking.

The rev die is definitely the same, I do believe the obv is as well with yours being slightly earlier.
