A friend of mine just pointed out this auction to me. For those of you that like numismatic books etc. To the best of my knowledge I am in no way related to the consignor (and do not know them). The earliest book is dated 1517. http://www.sothebys.com/en/auctions...on-books-coins-medals-antiquities-l16410.html
I have a few older and/or rarer numismatic books. I'm more interested in selling the ones I have than getting more, though lol.
