So if that had not been damage next to the steps it would have been considered an IDB?
Oh, interesting. I'll have to study more - thanks Impressive blob on that nickel!
I can't quite figure out if this is a cud or just a damaged coin. There seems to be a blob on the stairs to the right, but I can't get any closer...

I'm guessing this is also a split plate. Found this on another 1989...[ATTACH] [ATTACH]
Thanks Sal. Hmm, yeah, that example does show deterioration, doesn't it. Evan's right, I'll probably look back on this coin in a few years and...
