I don't know, but as I recall the original tutorial that played when starting Guild Wars for the first time mentioned that all unused medals would disappear at the end of the season, so I presume that Season 6 was simply the first time it was implemented.

Meanwhile I'm pissed off at my fellow guild members. First I carried them throughout the whole season, then we finished the last war of the season in the top 50 ... and gradually other guilds started spending their medals and pushed us into the mid-50s ... and most of my fellow guild members haven't spent any medals at all. Two spent some of their medals, but not all - the other five have done nothing ... and meanwhile we're just about assured of finishing top 50 if they spend their medals, and it looks like they've all decided to throw it all away. A month of me taking the time and making the effort to win this thing, and they're just going to throw it all away for nothing.
