My favourite coins (many of which aren't among my best, by some way) I would never want to part with, for all kinds of reasons including the sentimental. But I have others, which I wouldn't bat an eyelid about parting with. I kind of feel about them, "Ok, got that, seen the film, worn the T Shirt - what next?" Anyone else feel they could divide their collection in two : one lot that they'd never part with, the other that they could part with without too many qualms? And that the first lot doesn't necessarily include their finest specimens? I think that applies to most people. Some pieces are just too nice to sell, whilst with others you are ambivalent.
