I don't know if this is a recognized error coin. It kind of matches the DDO-001 on Coppercoins site but the die markers aren't there.
I don't think so. I'm looking at the L and I in liberty and yours don't seem to match the ones on coppercoins.com.
I know. It looks like dd on liBeRtY but the date could be MD. The split on top of G in god. I'm stashing it away in a 2x2. Who knows?
