I just received this coin that was broken during shipping. This is a good example of why you should at least use cardboard mailers ( I use Safe-T-Mailers ) when shipping ancient coins. I can't say it would not have broken if mailed in a cardboard mailer; but it would have had a better chance. It was mailed in a flip inside thin cardboard in a regular envelope. One problem, is that letters are sorted using machines, which can do this kind of damage to fragile items. That is why I use padded mailers that are non-machineable, meaning they are sorted by hand. The coin is nothing special and did not cost much, but I still hate to get broken coins.
