Aside from key dates, I'm not able to win any coins I want at auction (at reasonable prices). While I am only looking for NGC CAC coins currently, I end up paying way more than price guide for these. So if I'm up against dealers in some instances then the price guides should eventually reflect increases, but they do not it seems. Collector coins in my price range often show prices dropping, yet I have to pay more to own them. Of course the explanation for this is painfully obvious to me and explains why collectors leave the hobby.
