All used Japan. Have not counted them, but a rough guess is somewhere between $1,800 and 2,000 stamps...maybe more. There are two stock pages with earlier issues. The clear-view pages contain issues from the 1970s, 80s and 90s according to the original seller. Does not look like there is any duplication. Looks extremely clean. For accuracy, we did notice a less than 10 stamps with tiny faults. IMPORTANT: To hold postage costs down, the stamps will be removed from the pages and placed in glassine envelopes along with their year labels. Therefore, the pages are not part of the lot...only the stamps. If the lot is to be shipped overseas, registered mail WILL BE REQUIRED. Please wait for our invoice before making payment so registration charges can be included. If payment is made before invoice is sent, we reserve the right to request additional funds if necessary.
