I got a mailing from Ray Czahor (Cookie Jar Collectibles) for his Mail Bid Sale XV. It's all books -- 433 lots -- and many are obscure but intriguing. Ray is a specialist in the Philippines, but these books cover a variety of fields. The minimum bids are generally quite low. Clain-Stefanelli's 1968, 108-page "History of the National Numismatic Collections," e.g., has a M.B. of $2.50.
Ray still has his last sale, not this one, on his Web site. This sale doesn't close till Flag Day, June 14. You can e-mail cookiejarpi@verizon.net. The address is Box 597, Columbia MD 21045.
