MFD was at the Central States show and found one of the two IHC's I'm missing. It's an 1889 PCGS MS-64 RD. I'm surprised it's Red since the coin is almost 130 year old, but ....
Thanks for all of the kudos. I haven't dug out my Snow's guide so I don't have an S- number for it -- yet.
I looked at it at 9x and I don't see anything. No RPM or DDO/DDR. All I saw is a small die crack on the reverse. If I remember I'll take to the next Baltimore Whitman show (late June?) and ask Rick Snow. Maybe I've got a new one.
What a Great find! The Central States Show was my first coin show I've attended ever and it was fun, entertaining, informative, and educational. I missed a great educators talk and I could kick myself for missing it!
