I am offering some ancient-coin literature and catalogs for free, or nearly so. Take a look here: http://augustusmath.hypermart.net/Books.html to find Celators [all sold], Gorny and Mosch catalogs [seven left], M&M D catalogs [issues 1, 3, 8, and 22 remain], National Geographic issues with articles on the ancient world, all for just enough to cover my shipping (in the US only). The site also has many important scholarly reference works on which I reduced prices yesterday. My main ancient-coin literature site has more: http://augustusmath.hypermart.net/numislit.html
