This is a used bundle of 8 bundles (approximately 800 stamps) of 5-yen stamps featuring coal miners from the 1948 Industrial Design Series. Note: Over 20 years ago, I purchased 20 bundles (approximately 2,000 stamps) from a dealer. I looked through about half of them, intending to sort the rest later, but time passed. I no longer want to do the detailed work, so I am selling the remaining portion as is, from the time of purchase. Please be aware that these are unorganized and may contain a certain percentage of damaged stamps, and there may be slight discrepancies in the number of stamps.
