Yes, it's interesting to see which coins have eluded me. After 5 years or so of buying whatever comes up first, so long as it was better than I had, there are distinct gaps. If they had turned up, I would have bought them, so they obviously just didn't show. Time to get a bit more deliberate in my purchasing this year...as well as getting on some mailing lists. It's worth contacting a few old school dealers who not only are not on eBay, but aren't even on the internet, I think.
