I have boxes of world stamps. I've seen stamps in these boxes as old as the early 1900's with the latest dates in 1990's. With each lot, you'll get a least 500 good quality stamps to add to your collection all packed at random.
Some are used with cancels, some are new and have never been canceled, some have been mounted with hinges, some have never been mounted, some have plastic mounts covering them, some have mount pieces still attached.
Ask questions if you have any.
