What's up, folks? I hope everyone's enjoying their wknd. A long time ago, I started a casual penny collection where I'd toss Pennies here and there into a colossal jug. It filled w/ thousands of pennies, and on this rainy day, I figured I'd sort through them, see if I gathered something interesting over the years. THIS one, attached, jumped out at me. It's got a fairly clean strike on the obverse, but the reverse is totally blank, not even a silhouette nor severely worn down details, nothing at all, and the blank side feels very smooth. In the past, I've seen off-struck coins and planchets blank on both sides, but I've never seen something like this. So I'm truly not sure if this is a legit minting error OR if it might be a coin that's been manipulated by a prior owner. The first two photos were taken outdoors w/ the camera flash off, the last two outdoors w/ the camera flash on. Any opinions are much appreciated. Also, it weighs in at 2.8 grams.
That's a fairly common form of post-mint damage. Students in machine shop class will take a lathe and remove the reverse of the coin. It is not a mint error, and is not worth anything (its actually worth less than a penny, since half the coin has been removed).
