The prices in a guidebook are for US editions only. The guidebook cannot list foreign edition pricing because there are not enough books sold to get a base price from. I collect some foreign but usually by certain titles or illustrator or author. The price would only go as high as somone would pay. Certain books in the US that sell high would probably sell high in a foreign edition too....clear as mud but I hope this helps.
can you please tell me the difference in value of australian little golden book to the american variety! many if not most are first editions but a average price guide would be good as steve santis guide does not list the prices for these.
