1905 Edition of Munro's Coins of Japan

Just found this edition on eBay. Starting bid is $600. I've only seen three of these in the last 35 years, so I know it is rare. But it is a reprint of the original 1904 edition. I don't know why someone decided to reprint it in 1905. The 1904 Yokohama edition was a flop with very few copies sold. Munro just gave most of them away to people he knew. He even presented a copy to his mother. I own that copy. There was no need for a reprint.
