I was going through some of my quarters yesterday and I came across this interesting quarter and wanted to get your opinions on it. This coin is a 2003 D Missouri quarter The first thing to note is it appears to have been struck off centered, as you can see in these photos. Both on front and back of the coin. (Front) (Back) I did weigh the coin and it weighs somewhere around 5g. The scale seemed to either show 4g or 5g so I think it's right on the border of 5g, however, a normal quarter comes out to weigh 6g. (Coin on scale) Now, the more interesting part about this coin is its edge. As you can see in the next couple photos, the copper is recessed in a bit. The copper has the little ridges that are normally on the edge of the coin (hopefully you can that in the photos) which makes me think, in addition to the off centered striking, it may have been a minting error? (Edge of coin) The rational part of my brain is telling me either A.) What I'm seeing with the edge is post-mint damage and the "off centered" strike is wear and tear or B.) it might just be some sort of counterfeit coin. I'm very interested to hear what you all have to say about this and I can take more photos if needed. Thank you in advance!
