I order most of the coins I work with off of eBay and this happens a lot. I order a batch of coins from someone and they come in an envelope covered in a wide variety of stamps. Every time I get one of these I wonder if I’m getting someone’s legacy. Someone’s family member collected coins and stamps and after they’re gone a family member has to figure out what to do with the collection. They end up selling it off bit by bit on eBay. In some cases they use the stamps to ship the coins. I have no idea if that’s actually what happens, but whenever I get a package like this I always think that it is. A batch of beautiful Greek Athena coins came in this envelope.
