I'm a newbie to this site but not new to collecting anomalies and coins in general. I still can't distinguish small bead from large and a thousand other interesting questions about coins. I think I will love this site if I can figure it out.

Looks like there was a plating problem with the planchet.

"I still can't distinguish small bead from large"
An easy way to tell a Small Bead from a Large bead is to look at the space between the beads. If another bead will fit in the space, it is a Small Bead. If not, then it is a Large Bead.

My guess is PMD corrosion.
