"How times do change. I recall in the late 1970s being offered 1,000 - yes, one thousand - copies of Hibler & Kappen @$1.00 per copy and passing on the deal. These books were a drug on the market, dogs! Anyone acquainted with the numismatic literature marketplace knows the phenomenon well: when a book is in print or widely available you can't sell it; when it is out of print you can't buy it. Others more prescient than I bought the deal (in all, there were several thousand copies involved - the late Herb Melnick, I believe, was the seller) and the buyers issued a price supplement to enhance sales of the main work. The rest, as they say, is history."
