Seeing as this eBay Laughs thread has turned in to a discussion about proofs, I have a question for the assembled masses. I posted the link to the worn 27 florin because I thought it was a bit of a joke, I mean who would want a proof coin in that condition?? But as has been pointed out, proof is a method of striking, not an indication of condition, so, as has also been pointed out, perhaps those YEAR collectors only have one way to fill that gap, a low mintage proof in any condition - I guess I just didn't imagine that many, if any, proof coins would be circulated. My question is, I have 3 price guide books (Spink, CCGB and Coin Yearbook) and none of them quote the price of proofs in anything other than FDC - why is that? Please pardon my ignorance
